Test: Kingdom Monera - 2 - Question 1

Halophiles, methanogens and thermoacidophiles are

Detailed Solution for Test: Kingdom Monera - 2 - Question 1

Methanogens , Halophiles , Thermoacidophils , all belong to ARCHAEBACTERIA. They are primitive organisms which means they were the first to inhabit earth . They are often called LIVING FOSSILS. Methanogens are found in Rumen of cattles , Halophiles are found in salt lakes , Thermoacidophils are found in hot sulphur springs and Archaebacteria are found in some of the harsh climatic conditions where no other life form could survive.

Topic in NCERT: Archaebacteria

Line in NCERT: "These bacteria are special since they live in some of the most harsh habitats such as extreme salty areas (halophiles), hot springs (thermoacidophiles) and marshy areas (methanogens)."

Test: Kingdom Monera - 2 - Question 2

Causes of water bloom is :-

Detailed Solution for Test: Kingdom Monera - 2 - Question 2

These are a result of blue-green algae, which are actually bacteria (cyanobacteria). Some algal blooms are the result of an excess of nutrients (particularly phosphorus and nitrogen) in waters and higher concentrations of these nutrients in water cause increased growth of algae and green plants.

Test: Kingdom Monera - 2 - Question 3

Cyanobacteria is the new name of :-

Detailed Solution for Test: Kingdom Monera - 2 - Question 3

Cyanobacteria is the modern name of Myxophyceae. It is also called blue-green algae. It is a prokaryotic photosynthetic organism.

Topic in NCERT: Eubacteria

Line in NCERT: "The cyanobacteria (also referred to as blue-green algae) have chlorophyll a similar to green plants and are photosynthetic autotrophs."

Test: Kingdom Monera - 2 - Question 4

Bacteria reproduce in favourable condition by ___________

Detailed Solution for Test: Kingdom Monera - 2 - Question 4

Bacteria reproduce mainly by fission. Sometimes, under unfavourable conditions, they produce spores. They also reproduce by a sort of sexual reproduction by adopting a primitive type of DNA transfer from one bacterium to the other

Topic in NCERT: KINGDOM MONERA

Line in NCERT: "Bacteria reproduce mainly by fission. They also reproduce by a sort of sexual reproduction by adopting a primitive type of DNA transfer from one bacterium to the other."

Test: Kingdom Monera - 2 - Question 5

Photosynthetic autotrophic prokaryotic organism is:-

Detailed Solution for Test: Kingdom Monera - 2 - Question 5

cyanobacteria (also referred to as blue-green algae) have chlorophyll a similar to green plants and are photosynthetic autotrophs.The cyanobacteria are unicellular, colonial or filamentous, freshwater/marine or terrestrial algae. The colonies are generally surrounded by gelatinous sheath. They often form blooms in polluted water bodies. Some of these organisms can fix atmospheric nitrogen in specialised cells called heterocysts, e.g., Nostoc and Anabaena.

Topic in NCERT: Eubacteria

Line in NCERT: "The cyanobacteria (also referred to as blue-green algae) have chlorophyll a similar to green plants and are photosynthetic autotrophs."

Test: Kingdom Monera - 2 - Question 6

Which of the following are wall less prokaryote?

Detailed Solution for Test: Kingdom Monera - 2 - Question 6

Mycoplasma is a prokaryote having no cell wall so they are also called "bacteria with their coats off".They are resistant to penicillin because penicillin acts as a cell wall and they are wall less.

Topic in NCERT: KINGDOM MONERA

Line in NCERT: "The Mycoplasma are organisms that completely lack a cell wall."

Test: Kingdom Monera - 2 - Question 7

Most common method of reproduction in prokaryotes is:-

Detailed Solution for Test: Kingdom Monera - 2 - Question 7

Fission or Binary fission ("division in half") is a kind of asexual reproduction. It is the most common form of reproduction in prokaryotes such as bacteria. It occurs in some single-celled Eukaryotes like the Amoeba and the Paramoecium. In binary fission, DNA replication and segregation occur simultaneously.

Topic in NCERT: KINGDOM MONERA

Line in NCERT: "Bacteria reproduce mainly by fission (Figure 2.3)."

Test: Kingdom Monera - 2 - Question 8

identify the correct statement 

STATEMENT I :  Halophiles are eubacteria living  in salty areas

STATEMENT II  :Methanogens are abudant in guts of ruminants .

STATEMENT III : Thermoacidophiles are bacteria living in hot springs 

Detailed Solution for Test: Kingdom Monera - 2 - Question 8

- Correct Answer: B: BOTH II AND III
- Explanation:

 

STATEMENT I : Halophiles are eubacteria living  in salty areas - HALOPHILES are archaebacteria not eubacteria 
- Statement II: Methanogens are indeed abundant in the guts of ruminants. These are a group of archaea that produce methane as a byproduct of metabolism in the digestive systems of ruminant animals like cows.
- Statement III: Thermoacidophiles are bacteria that thrive in hot, acidic environments like hot springs, demonstrating their ability to survive in extreme conditions.

Topic in NCERT: Archaebacteria

Line in NCERT: "These bacteria are special since they live in some of the most harsh habitats such as extreme salty areas (halophiles), hot springs (thermoacidophiles) and marshy areas (methanogens)."

Test: Kingdom Monera - 2 - Question 9

Harmful activity of Blue green algae is:-

Detailed Solution for Test: Kingdom Monera - 2 - Question 9

Cyanobacteria often form blooms in polluted water bodies. Some of these organisms can fix atmospheric nitrogen in specialised cells called heterocysts, e.g., Nostoc and Anabaena

Topic in NCERT: Slime Moulds

Line in NCERT: "they often form blooms in polluted water bodies."

Test: Kingdom Monera - 2 - Question 10

What do chemosynthetic autotrophic bacteria oxidize for their ATP production?

Detailed Solution for Test: Kingdom Monera - 2 - Question 10

Chemosynthetic autotrophic bacteria oxidize inorganic substances for their ATP production.

Topic in NCERT: Eubacteria

Line in NCERT: "Chemosynthetic autotrophic bacteria oxidise various inorganic substances such as nitrates, nitrites and ammonia and use the released energy for their ATP production."
