FAQs on Kingdom Monera: Archaebacteria & Eubacteria Video Lecture - Biology Class 11 - NEET
| 1. What is the difference between Archaebacteria and Eubacteria? |  |
Ans. Archaebacteria and Eubacteria are two domains of Kingdom Monera, but they have distinct characteristics. Archaebacteria are known for their ability to survive in extreme environments, such as hot springs and acidic environments, while Eubacteria are found in more diverse habitats. Additionally, Archaebacteria have different cell wall composition compared to Eubacteria, as they lack peptidoglycan in their cell walls.
| 2. How do Archaebacteria and Eubacteria obtain energy? | |
Ans. Archaebacteria and Eubacteria obtain energy through different methods. Archaebacteria can be autotrophs, meaning they can produce their own food through photosynthesis or chemosynthesis. Some Archaebacteria can also be heterotrophs and obtain energy by consuming organic matter. On the other hand, Eubacteria can be autotrophs or heterotrophs, depending on the species. Autotrophic Eubacteria use photosynthesis or chemosynthesis, while heterotrophic Eubacteria obtain energy by consuming organic matter.
| 3. Can Archaebacteria and Eubacteria cause diseases in humans? | |
Ans. Yes, both Archaebacteria and Eubacteria can cause diseases in humans. However, the majority of disease-causing bacteria belong to the domain Eubacteria. Examples of Eubacteria that cause diseases include Escherichia coli, Salmonella, and Streptococcus. Archaebacteria, on the other hand, are not commonly associated with human diseases. They are more known for their role in extreme environments and their importance in various ecological processes.
| 4. Are Archaebacteria and Eubacteria sensitive to antibiotics? | |
Ans. Yes, Eubacteria are generally sensitive to antibiotics, and these medications are commonly used to treat bacterial infections. However, Archaebacteria are often resistant to antibiotics that target Eubacteria. This is because Archaebacteria have different cellular structures and biochemical processes compared to Eubacteria. Therefore, antibiotics that are effective against Eubacteria may not be effective against Archaebacteria.
| 5. Can Archaebacteria and Eubacteria be found in the human body? | |
Ans. Yes, both Archaebacteria and Eubacteria can be found in the human body. Eubacteria, in particular, are abundant in various parts of our body, such as the skin, mouth, and intestines. Some Eubacteria play important roles in maintaining our health, while others can cause infections. Archaebacteria are also present in small numbers in certain body sites, but their role in human health is not yet fully understood.

0:0:0: have you ever found yourself curled up
0:0:2: in bed feeling miserable due to a
0:0:4: bacterial infection
0:0:6: it's nothing but a bad bacteria present
0:0:9: in our environment
0:0:11: on the other hand have you heard about
0:0:13: the good bacteria that are often talked
0:0:15: about
0:0:16: like in curd or in our gut that helps in
0:0:19: digestion
0:0:21: but wait we were supposed to discuss
0:0:23: Kingdom Monera but why did we start with
0:0:25: bacteria
0:0:27: so let me break the ice for you
0:0:30: all these harmful and helpful bacteria
0:0:33: that we just talked about are classified
0:0:35: under the kingdom Monera
0:0:37: so if we have to study Kingdom Monera
0:0:40: it's really important to understand
0:0:42: bacteria first
0:0:44: these tiny single-celled organisms are
0:0:47: so unique that they have their own
0:0:48: biological Kingdom that is Kingdom
0:0:50: Monera
0:0:52: bacteria are found in almost every
0:0:54: environment on Earth from soil to water
0:0:56: to the human gut
0:0:58: bacteria are some of the oldest forms of
0:1:1: life on Earth
0:1:2: they have been around for billions of
0:1:5: years and are believed to have played a
0:1:7: crucial role in shaping the planet's
0:1:9: atmosphere and environment also
0:1:11: bacteria are tiny single-celled
0:1:14: organisms that come in different shapes
0:1:16: and sizes
0:1:18: scientists group bacteria into four
0:1:20: categories based on their shape
0:1:23: the first category is caucus cocky these
0:1:26: bacteria are spherical or oval in shape
0:1:29: these can be micrococcus single
0:1:32: diplococcus in pairs tetrachopters in
0:1:36: force streptococcus in Chains and
0:1:39: staphylococcus in clusters like grapes
0:1:42: the second is the rod-shaped bacteria
0:1:44: called bacillus bacilli they can be with
0:1:47: or without flagella
0:1:49: the third is the coma shaped bacteria
0:1:51: called wide room we Brew these are small
0:1:53: bacteria with flagella at one end
0:1:56: the fourth is the spiral-shaped bacteria
0:1:59: called spivolim spirula they are rigid
0:2:1: forms due to the spiral structure and
0:2:3: bear flagella at one or both the ends
0:2:7: bacteria may have a simple structure but
0:2:10: they are actually quite complex in
0:2:12: Behavior
0:2:13: these tiny organisms are incredibly
0:2:16: diverse in their metabolic abilities
0:2:18: which means they can do many different
0:2:20: things with the food they consume
0:2:22: some bacteria are even able to create
0:2:25: their own food from inorganic substances
0:2:28: this process is called autotrophy and
0:2:31: there are two types of autotrophs first
0:2:34: photosynthetic autotrophs use sunlight
0:2:36: to make their food while chemosynthetic
0:2:38: autotrophs use chemicals to create their
0:2:41: own energy
0:2:42: most bacteria however are heterotrophs
0:2:47: this means that they rely on other
0:2:49: organisms or dead organic matter for
0:2:51: their food
0:2:53: they break down these substances into
0:2:55: smaller pieces which they can then use
0:2:57: for energy
0:2:59: bacteria are able to do this in many
0:3:1: different ways such as by secreting
0:3:4: enzymes that break down complex
0:3:6: molecules or by engulfing other
0:3:8: organisms and breaking them down inside
0:3:11: their own cells
0:3:13: now that you have understood bacteria
0:3:16: it's time to understand how they are
0:3:18: classified
0:3:19: Kingdom Monera is classified into two
0:3:22: sub-kingdoms archibacteria and your
0:3:24: bacteria
0:3:25: in Eubacteria we will study
0:3:28: cyanobacteria chemosynthetic bacteria
0:3:30: heterotrophic bacteria and mycoplasma
0:3:34: let's take a look at each of these by
0:3:36: asking a simple question
0:3:38: did you know that some bacteria are so
0:3:41: tough that they can survive in the
0:3:42: harshest of environments like extreme
0:3:45: salty areas hot springs and Marshy areas
0:3:49: these tough bacteria are none other than
0:3:52: but are archibacteria these are some of
0:3:54: the oldest living organisms on Earth
0:3:57: they have been around for over 3.5
0:4:0: billion years and they are different
0:4:2: from other bacteria because of their
0:4:4: unique cell wall structure
0:4:6: this feature helps them to survive in
0:4:8: extreme conditions that would be deadly
0:4:10: to other bacteria
0:4:12: for example some archibacteria called
0:4:15: halophiles can survive in extremely
0:4:17: salty conditions such as in the Dead Sea
0:4:20: or in salt pans
0:4:22: other archibacteria cause
0:4:24: thermoacidophiles can survive in hot and
0:4:27: acidic environments such as in volcanic
0:4:29: Hot Springs
0:4:31: and yet other archibacteria called
0:4:33: methanogens can survive in oxygen-free
0:4:35: environments and produce methane gas as
0:4:38: a byproduct of their metabolism in fact
0:4:40: methanogens are present in the guts of
0:4:43: ruminant animals like cows and Buffalos
0:4:45: and are responsible for the production
0:4:47: of biogas from their dung
0:4:50: and now let's study the applications of
0:4:53: archibacteria as they have important
0:4:55: biotechnological applications such as in
0:4:58: the production of enzymes for industrial
0:5:0: and medical use
0:5:2: some archibacteria can even survive in
0:5:5: radioactive environments and are being
0:5:7: studied for their potential use in
0:5:9: nuclear waste management
0:5:12: now coming to the sub Kingdom Eubacteria
0:5:15: it is also known as true bacteria a
0:5:18: single-celled organisms that belong to
0:5:20: the kingdom Monera
0:5:22: they are one of the most diverse groups
0:5:24: of organisms on Earth and can be found
0:5:27: in virtually every environment from Deep
0:5:29: Sea Winds to the human gut
0:5:32: Eubacteria are important to study
0:5:34: because they have a significant impact
0:5:36: on the world around us
0:5:38: some bacteria are beneficial and perform
0:5:41: vital functions such as aiding in
0:5:43: digestion While others can cause serious
0:5:46: illnesses
0:5:47: the study of Eubacteria is essential for
0:5:50: understanding how these organisms
0:5:52: interact with their environment and
0:5:54: other living beings
0:5:55: one fascinating aspect of your bacteria
0:5:58: is their ability to adapt and evolve
0:6:0: rapidly
0:6:2: this has allowed them to develop
0:6:4: resistance to antibiotics which can make
0:6:6: treating bacterial infections more
0:6:8: challenging
0:6:10: scientists are working to find new ways
0:6:12: to combat these bacteria and prevent the
0:6:15: spread of antibiotic resistant strains
0:6:19: Eubacteria are super small but they come
0:6:21: in all sorts of different types
0:6:24: you can recognize them by their rigid
0:6:26: cell walls and some of them even have a
0:6:29: tiny tail called the flagellum that
0:6:31: helps them move around
0:6:33: now let's talk about some different
0:6:35: kinds of bacteria classified under
0:6:37: Eubacteria
0:6:39: one type of Eubacteria is called
0:6:41: cyanobacteria but you might know them as
0:6:44: blue-green algae
0:6:45: these little guys are really interesting
0:6:48: because they can make their own food
0:6:50: through a process called photosynthesis
0:6:52: just like plants
0:6:54: they have a green pigment called
0:6:56: chlorophyllate that helps them do this
0:6:58: and that's why they are photosynthetic
0:7:0: autotrophs
0:7:2: cyanobacteria are single-celled
0:7:4: organisms and can be found all over the
0:7:7: place in fresh water in Marine water on
0:7:10: land and even in colonies with a
0:7:12: jelly-like coating around them called a
0:7:14: gelatinous sheath
0:7:15: sometimes when they live in polluted
0:7:18: water they can grow super fast and
0:7:20: create big blooms but here is the
0:7:23: coolest part some types of cyanobacteria
0:7:26: can take nitrogen from the air and turn
0:7:28: it into a form that plants can use to
0:7:30: grow
0:7:31: they do this in special cells called
0:7:34: heterosis and two examples of this type
0:7:36: of cyanobacteria are not stock and
0:7:39: anabena
0:7:40: as we already talked about the
0:7:42: chemosynthetic bacteria at the start of
0:7:44: the video these little guys are really
0:7:47: cool because they can make their own
0:7:49: food without using sunlight like plants
0:7:51: too
0:7:52: instead they get their energy by
0:7:55: breaking down certain chemicals like
0:7:57: nitrates nitrites and ammonia
0:8:0: when the bacteria break down these
0:8:2: chemicals they release energy that they
0:8:5: use to make a molecule called ATP which
0:8:7: is like their own personal battery
0:8:10: this process is called oxidation
0:8:13: but here is the really interesting part
0:8:15: these bacteria are essential for
0:8:17: recycling important nutrients like
0:8:20: nitrogen phosphorus iron and sulfur
0:8:24: without them these nutrients would just
0:8:26: stay trapped in dead plant and animal
0:8:28: matter and the ecosystem would suffer
0:8:32: so while they may be small and hard to
0:8:34: see chemosynthetic autotrophic bacteria
0:8:37: play a huge role in keeping our world
0:8:39: healthy and thriving
0:8:41: you will be amazed to know that some or
0:8:43: other kinds of bacterias are all around
0:8:46: us and are actually the most common type
0:8:48: of bacteria in nature
0:8:50: these are none other than a
0:8:52: heterotrophic bacteria
0:8:54: these little guys again play a really
0:8:56: important role in breaking down their
0:8:59: plant and animal matter which helps keep
0:9:1: the ecosystem healthy
0:9:3: but heterotrophic bacteria are also
0:9:6: really important to us humans
0:9:8: they can help us make things like curd
0:9:11: from milk and even produce life-saving
0:9:13: antibiotics
0:9:15: heterotrophic bacteria are also able to
0:9:17: fix nitrogen in the roots of legumes
0:9:20: which can help the plant to thrive
0:9:23: unfortunately not all heterotrophic
0:9:25: bacteria are friendly
0:9:28: some can cause serious harm to humans
0:9:30: crops and animals
0:9:33: you have probably heard of diseases like
0:9:35: cholera typhoid and tetanus which are
0:9:38: all caused by different types of
0:9:40: bacteria
0:9:41: and there is even a disease called
0:9:43: Citrus cancer that affects citrus fruits
0:9:46: when it comes to reproduction bacteria
0:9:49: mainly reproduced by fission which means
0:9:51: they split into two identical copies of
0:9:54: themselves
0:9:55: but under really tough conditions they
0:9:58: can also create spores
0:10:0: and in a really interesting process
0:10:2: bacteria can even transfer DNA from one
0:10:5: to another almost like a primitive form
0:10:7: of sexual reproduction
0:10:9: so while heterotrophic bacteria may be
0:10:12: tiny and hard to see they have a huge
0:10:14: impact on the world around us both good
0:10:17: and bad mycoplasma are teeny tiny living
0:10:20: things that don't have a cell wall
0:10:23: they are so small that they are actually
0:10:25: the smallest cells we know of
0:10:28: what's really amazing about them is that
0:10:30: they don't even need oxygen to survive
0:10:34: some types of mycoplasma can make
0:10:36: animals and plants sick which we call
0:10:38: pathogenic
0:10:40: to understand what a cell wall is it's
0:10:42: like a protective layer that surrounds
0:10:44: most cells kind of like a suit of armor
0:10:48: but mycoplasma are unique because they
0:10:50: don't have this suit of armor their
0:10:52: naked cells
0:10:54: even though they're small and don't have
0:10:56: a cell wall mycoplasma are still alive
0:10:59: and can do a lot of things that other
0:11:1: cells can do
0:11:3: however because they don't have a cell
0:11:5: wall they can be a bit sneaky and cause
0:11:8: problems in animals and plants by
0:11:10: infecting them
0:11:12: so till now you understood all about the
0:11:14: kingdom Monera and its sub kingdoms
0:11:17: archibacteria and Eubacteria
0:11:19: now you know how important these
0:11:21: bacteria are for our Earth and for us
0:11:24: like lactic acid bacteria incurred
0:11:27: but these bacteria are capable of
0:11:29: causing harm too like mycobacterium
0:11:31: tuberculosis which causes TB so beware
0:11:34: of bad ones from now on
0:11:37: now as you have completed this topic
0:11:40: you can learn it with chapter notes
0:11:42: watch video lectures and solve ncrt
0:11:45: based McQ tests of this chapter on
0:11:48: edurev
0:11:49: and this is available not just for one
0:11:52: but all the chapters of class 11 and 12
0:11:54: biology and much more for your neat
0:11:57: preparation
0:0:2: in bed feeling miserable due to a
0:0:4: bacterial infection
0:0:6: it's nothing but a bad bacteria present
0:0:9: in our environment
0:0:11: on the other hand have you heard about
0:0:13: the good bacteria that are often talked
0:0:15: about
0:0:16: like in curd or in our gut that helps in
0:0:19: digestion
0:0:21: but wait we were supposed to discuss
0:0:23: Kingdom Monera but why did we start with
0:0:25: bacteria
0:0:27: so let me break the ice for you
0:0:30: all these harmful and helpful bacteria
0:0:33: that we just talked about are classified
0:0:35: under the kingdom Monera
0:0:37: so if we have to study Kingdom Monera
0:0:40: it's really important to understand
0:0:42: bacteria first
0:0:44: these tiny single-celled organisms are
0:0:47: so unique that they have their own
0:0:48: biological Kingdom that is Kingdom
0:0:50: Monera
0:0:52: bacteria are found in almost every
0:0:54: environment on Earth from soil to water
0:0:56: to the human gut
0:0:58: bacteria are some of the oldest forms of
0:1:1: life on Earth
0:1:2: they have been around for billions of
0:1:5: years and are believed to have played a
0:1:7: crucial role in shaping the planet's
0:1:9: atmosphere and environment also
0:1:11: bacteria are tiny single-celled
0:1:14: organisms that come in different shapes
0:1:16: and sizes
0:1:18: scientists group bacteria into four
0:1:20: categories based on their shape
0:1:23: the first category is caucus cocky these
0:1:26: bacteria are spherical or oval in shape
0:1:29: these can be micrococcus single
0:1:32: diplococcus in pairs tetrachopters in
0:1:36: force streptococcus in Chains and
0:1:39: staphylococcus in clusters like grapes
0:1:42: the second is the rod-shaped bacteria
0:1:44: called bacillus bacilli they can be with
0:1:47: or without flagella
0:1:49: the third is the coma shaped bacteria
0:1:51: called wide room we Brew these are small
0:1:53: bacteria with flagella at one end
0:1:56: the fourth is the spiral-shaped bacteria
0:1:59: called spivolim spirula they are rigid
0:2:1: forms due to the spiral structure and
0:2:3: bear flagella at one or both the ends
0:2:7: bacteria may have a simple structure but
0:2:10: they are actually quite complex in
0:2:12: Behavior
0:2:13: these tiny organisms are incredibly
0:2:16: diverse in their metabolic abilities
0:2:18: which means they can do many different
0:2:20: things with the food they consume
0:2:22: some bacteria are even able to create
0:2:25: their own food from inorganic substances
0:2:28: this process is called autotrophy and
0:2:31: there are two types of autotrophs first
0:2:34: photosynthetic autotrophs use sunlight
0:2:36: to make their food while chemosynthetic
0:2:38: autotrophs use chemicals to create their
0:2:41: own energy
0:2:42: most bacteria however are heterotrophs
0:2:47: this means that they rely on other
0:2:49: organisms or dead organic matter for
0:2:51: their food
0:2:53: they break down these substances into
0:2:55: smaller pieces which they can then use
0:2:57: for energy
0:2:59: bacteria are able to do this in many
0:3:1: different ways such as by secreting
0:3:4: enzymes that break down complex
0:3:6: molecules or by engulfing other
0:3:8: organisms and breaking them down inside
0:3:11: their own cells
0:3:13: now that you have understood bacteria
0:3:16: it's time to understand how they are
0:3:18: classified
0:3:19: Kingdom Monera is classified into two
0:3:22: sub-kingdoms archibacteria and your
0:3:24: bacteria
0:3:25: in Eubacteria we will study
0:3:28: cyanobacteria chemosynthetic bacteria
0:3:30: heterotrophic bacteria and mycoplasma
0:3:34: let's take a look at each of these by
0:3:36: asking a simple question
0:3:38: did you know that some bacteria are so
0:3:41: tough that they can survive in the
0:3:42: harshest of environments like extreme
0:3:45: salty areas hot springs and Marshy areas
0:3:49: these tough bacteria are none other than
0:3:52: but are archibacteria these are some of
0:3:54: the oldest living organisms on Earth
0:3:57: they have been around for over 3.5
0:4:0: billion years and they are different
0:4:2: from other bacteria because of their
0:4:4: unique cell wall structure
0:4:6: this feature helps them to survive in
0:4:8: extreme conditions that would be deadly
0:4:10: to other bacteria
0:4:12: for example some archibacteria called
0:4:15: halophiles can survive in extremely
0:4:17: salty conditions such as in the Dead Sea
0:4:20: or in salt pans
0:4:22: other archibacteria cause
0:4:24: thermoacidophiles can survive in hot and
0:4:27: acidic environments such as in volcanic
0:4:29: Hot Springs
0:4:31: and yet other archibacteria called
0:4:33: methanogens can survive in oxygen-free
0:4:35: environments and produce methane gas as
0:4:38: a byproduct of their metabolism in fact
0:4:40: methanogens are present in the guts of
0:4:43: ruminant animals like cows and Buffalos
0:4:45: and are responsible for the production
0:4:47: of biogas from their dung
0:4:50: and now let's study the applications of
0:4:53: archibacteria as they have important
0:4:55: biotechnological applications such as in
0:4:58: the production of enzymes for industrial
0:5:0: and medical use
0:5:2: some archibacteria can even survive in
0:5:5: radioactive environments and are being
0:5:7: studied for their potential use in
0:5:9: nuclear waste management
0:5:12: now coming to the sub Kingdom Eubacteria
0:5:15: it is also known as true bacteria a
0:5:18: single-celled organisms that belong to
0:5:20: the kingdom Monera
0:5:22: they are one of the most diverse groups
0:5:24: of organisms on Earth and can be found
0:5:27: in virtually every environment from Deep
0:5:29: Sea Winds to the human gut
0:5:32: Eubacteria are important to study
0:5:34: because they have a significant impact
0:5:36: on the world around us
0:5:38: some bacteria are beneficial and perform
0:5:41: vital functions such as aiding in
0:5:43: digestion While others can cause serious
0:5:46: illnesses
0:5:47: the study of Eubacteria is essential for
0:5:50: understanding how these organisms
0:5:52: interact with their environment and
0:5:54: other living beings
0:5:55: one fascinating aspect of your bacteria
0:5:58: is their ability to adapt and evolve
0:6:0: rapidly
0:6:2: this has allowed them to develop
0:6:4: resistance to antibiotics which can make
0:6:6: treating bacterial infections more
0:6:8: challenging
0:6:10: scientists are working to find new ways
0:6:12: to combat these bacteria and prevent the
0:6:15: spread of antibiotic resistant strains
0:6:19: Eubacteria are super small but they come
0:6:21: in all sorts of different types
0:6:24: you can recognize them by their rigid
0:6:26: cell walls and some of them even have a
0:6:29: tiny tail called the flagellum that
0:6:31: helps them move around
0:6:33: now let's talk about some different
0:6:35: kinds of bacteria classified under
0:6:37: Eubacteria
0:6:39: one type of Eubacteria is called
0:6:41: cyanobacteria but you might know them as
0:6:44: blue-green algae
0:6:45: these little guys are really interesting
0:6:48: because they can make their own food
0:6:50: through a process called photosynthesis
0:6:52: just like plants
0:6:54: they have a green pigment called
0:6:56: chlorophyllate that helps them do this
0:6:58: and that's why they are photosynthetic
0:7:0: autotrophs
0:7:2: cyanobacteria are single-celled
0:7:4: organisms and can be found all over the
0:7:7: place in fresh water in Marine water on
0:7:10: land and even in colonies with a
0:7:12: jelly-like coating around them called a
0:7:14: gelatinous sheath
0:7:15: sometimes when they live in polluted
0:7:18: water they can grow super fast and
0:7:20: create big blooms but here is the
0:7:23: coolest part some types of cyanobacteria
0:7:26: can take nitrogen from the air and turn
0:7:28: it into a form that plants can use to
0:7:30: grow
0:7:31: they do this in special cells called
0:7:34: heterosis and two examples of this type
0:7:36: of cyanobacteria are not stock and
0:7:39: anabena
0:7:40: as we already talked about the
0:7:42: chemosynthetic bacteria at the start of
0:7:44: the video these little guys are really
0:7:47: cool because they can make their own
0:7:49: food without using sunlight like plants
0:7:51: too
0:7:52: instead they get their energy by
0:7:55: breaking down certain chemicals like
0:7:57: nitrates nitrites and ammonia
0:8:0: when the bacteria break down these
0:8:2: chemicals they release energy that they
0:8:5: use to make a molecule called ATP which
0:8:7: is like their own personal battery
0:8:10: this process is called oxidation
0:8:13: but here is the really interesting part
0:8:15: these bacteria are essential for
0:8:17: recycling important nutrients like
0:8:20: nitrogen phosphorus iron and sulfur
0:8:24: without them these nutrients would just
0:8:26: stay trapped in dead plant and animal
0:8:28: matter and the ecosystem would suffer
0:8:32: so while they may be small and hard to
0:8:34: see chemosynthetic autotrophic bacteria
0:8:37: play a huge role in keeping our world
0:8:39: healthy and thriving
0:8:41: you will be amazed to know that some or
0:8:43: other kinds of bacterias are all around
0:8:46: us and are actually the most common type
0:8:48: of bacteria in nature
0:8:50: these are none other than a
0:8:52: heterotrophic bacteria
0:8:54: these little guys again play a really
0:8:56: important role in breaking down their
0:8:59: plant and animal matter which helps keep
0:9:1: the ecosystem healthy
0:9:3: but heterotrophic bacteria are also
0:9:6: really important to us humans
0:9:8: they can help us make things like curd
0:9:11: from milk and even produce life-saving
0:9:13: antibiotics
0:9:15: heterotrophic bacteria are also able to
0:9:17: fix nitrogen in the roots of legumes
0:9:20: which can help the plant to thrive
0:9:23: unfortunately not all heterotrophic
0:9:25: bacteria are friendly
0:9:28: some can cause serious harm to humans
0:9:30: crops and animals
0:9:33: you have probably heard of diseases like
0:9:35: cholera typhoid and tetanus which are
0:9:38: all caused by different types of
0:9:40: bacteria
0:9:41: and there is even a disease called
0:9:43: Citrus cancer that affects citrus fruits
0:9:46: when it comes to reproduction bacteria
0:9:49: mainly reproduced by fission which means
0:9:51: they split into two identical copies of
0:9:54: themselves
0:9:55: but under really tough conditions they
0:9:58: can also create spores
0:10:0: and in a really interesting process
0:10:2: bacteria can even transfer DNA from one
0:10:5: to another almost like a primitive form
0:10:7: of sexual reproduction
0:10:9: so while heterotrophic bacteria may be
0:10:12: tiny and hard to see they have a huge
0:10:14: impact on the world around us both good
0:10:17: and bad mycoplasma are teeny tiny living
0:10:20: things that don't have a cell wall
0:10:23: they are so small that they are actually
0:10:25: the smallest cells we know of
0:10:28: what's really amazing about them is that
0:10:30: they don't even need oxygen to survive
0:10:34: some types of mycoplasma can make
0:10:36: animals and plants sick which we call
0:10:38: pathogenic
0:10:40: to understand what a cell wall is it's
0:10:42: like a protective layer that surrounds
0:10:44: most cells kind of like a suit of armor
0:10:48: but mycoplasma are unique because they
0:10:50: don't have this suit of armor their
0:10:52: naked cells
0:10:54: even though they're small and don't have
0:10:56: a cell wall mycoplasma are still alive
0:10:59: and can do a lot of things that other
0:11:1: cells can do
0:11:3: however because they don't have a cell
0:11:5: wall they can be a bit sneaky and cause
0:11:8: problems in animals and plants by
0:11:10: infecting them
0:11:12: so till now you understood all about the
0:11:14: kingdom Monera and its sub kingdoms
0:11:17: archibacteria and Eubacteria
0:11:19: now you know how important these
0:11:21: bacteria are for our Earth and for us
0:11:24: like lactic acid bacteria incurred
0:11:27: but these bacteria are capable of
0:11:29: causing harm too like mycobacterium
0:11:31: tuberculosis which causes TB so beware
0:11:34: of bad ones from now on
0:11:37: now as you have completed this topic
0:11:40: you can learn it with chapter notes
0:11:42: watch video lectures and solve ncrt
0:11:45: based McQ tests of this chapter on
0:11:48: edurev
0:11:49: and this is available not just for one
0:11:52: but all the chapters of class 11 and 12
0:11:54: biology and much more for your neat
0:11:57: preparation
