Bacteria are grouped under four categories according to their shape. Study the given figures and select the correct option regarding this.

Detailed Solution for Test: Kingdom Monera (NCERT) - Question 3

Bacteria are grouped under four categories based on their shapes: the spherical coccus (pl.: coccl), the rod-shaped bacillus (pi.: bacilli), the comma-shaped vibrium (pl.: vibrio) and the spiral spirillum (pl.: spirilla).

Test: Kingdom Monera (NCERT) - Question 4

Read the following statements regarding methanogens and select the correct option.
(i) They are included in the group Archaebacteria.
(ii) They are responsible for the production of biogas in gobar gas plants.
(iii) They live in hot sulphur springs.
(iv) They are strictly anaerobic.

Detailed Solution for Test: Kingdom Monera (NCERT) - Question 4

(i) They are included in the group Archaebacteria.

Correct. The content mentions, "Archaebacteria differ from other bacteria in having a different cell wall structure."
(ii) They are responsible for the production of biogas in gobar gas plants.

Correct. The content states, "Methanogens are present in the gut of several ruminant animals...and they are responsible for the production of methane (biogas) from the dung of these animals."
(iii) They live in hot sulphur springs.

Incorrect. The content says, "These bacteria live in some of the most harsh habitats such as...hot springs (thermoacidophiles) and marshy areas (methanogens)." Methanogens are not specified to live in hot sulphur springs; thermoacidophiles do.
(iv) They are strictly anaerobic.

Correct. Methanogens, by their nature, are anaerobic as they produce methane in the absence of oxygen.

Test: Kingdom Monera (NCERT) - Question 5

Given figure is of filamentous blue green alga Nostoc Identify the parts marked as A and B and select the correct option.

Detailed Solution for Test: Kingdom Monera (NCERT) - Question 5

Nostoc occurs in both aquatic and subaerial habitats. A dense mucilage covering (labelled as B in the given figure) is present on the outside. Each trichome is beaded, S-shaped and consists of a large number of vegetative cells, a few term in a land intercalary large pale coloured heterocysts - (labelled as A in the given figure) and thick-walled resting cells called akinetes. Heterocysts are specialised to perform nitrogen fixation.

Test: Kingdom Monera (NCERT) - Question 6

Which of the following statements is incorrect regarding the structure of a typical bacterial cell?

Detailed Solution for Test: Kingdom Monera (NCERT) - Question 6

In a bacterial cell, membrane bound cell organelles as found in eukaryotes are absent. Various structures present in the cytoplasm of a prokaryotic cell include mesosomes, 70S ribosomes, nucleoid, plasmids, gas vacuoles, food reserve, etc.

Test: Kingdom Monera (NCERT) - Question 7

______ is the most common method of reproduction in bacteria.

Detailed Solution for Test: Kingdom Monera (NCERT) - Question 7

Reproduction in bacteria occurs by three methods - binary fission, sporulation and sexual reproduction. Binary fission is the most common method of bacterial multiplication under favourable conditions, in which a mature bacterium divides into two equal daughter cells.

Test: Kingdom Monera (NCERT) - Question 8

Cyanobacteria are classified under which of the following kingdoms?

Detailed Solution for Test: Kingdom Monera (NCERT) - Question 8

Cyano bacteria or blue-green algae are Gram + photosynthetic prokaryotes which perform oxygenic photo- synthesis. Photosynthetic pigments include chlorophyll a, carotenoids  and phycobilins. Cyanobacteria are classified under kingdom Monera. Cyanobacterial cell structure is  typically prokaryotic - one envelope organisation with peptidoglycan wall, naked DNA, 70S ribosomes and absence of membrane bound structures like endoplasmic reticulum, mltochondria, Golgi bodies, plastids, lysosomes, sap vacuoles. The outer part of the protoplast, called chromoplasm, contains a number of photosynthetic thylakoids.

Test: Kingdom Monera (NCERT) - Question 9

How do cyanobacteria perform photosynthesis?

Detailed Solution for Test: Kingdom Monera (NCERT) - Question 9

Cyanobacteria have chlorophyll-a, similar to green plants, which allows them to perform photosynthesis. They are photosynthetic autotrophs and can be unicellular, colonial, or filamentous algae.

Test: Kingdom Monera (NCERT) - Question 10

Read the following statements and select the correct option.
Statement 1: Almost all bacteria possess lipoproteinaceous plasma membrane.
Statement 2: The plasma membrane of archaebacteria as well as eubacteria have same type of lipids.

Detailed Solution for Test: Kingdom Monera (NCERT) - Question 10

Bacterial plasma membrane or plasmalemma has a structure similar to that of a typical membrane. It is made of a phospholipid bilayer with proteins of various types (extrinsic, integral, transmembrane). Archaebacteria are a group of most primitive prokaryotes which are able te survive in extremely hostile conditions. Their cell membranes are different from eubacteria and are characterized by the presence of a monolayer of branched chain lipids.

Test: Kingdom Monera (NCERT) - Question 11

Which group of bacteria lacks a cell wall and can survive without oxygen?

Detailed Solution for Test: Kingdom Monera (NCERT) - Question 11

Mycoplasma are unique among bacteria because they completely lack a cell wall, making them the smallest living cells known. They can survive without oxygen, and many of them are pathogenic in animals and plants.

Test: Kingdom Monera (NCERT) - Question 12

Cyanobacteria are used in agricultural fields for improvement because they cause

Detailed Solution for Test: Kingdom Monera (NCERT) - Question 12

Several cyanobacteria have the ability of nitrogen fixation. The filamentous forms possess special large pale cells or heterocysts for this. Some of the fixed nitrogen comes out as excretion. After death of cyanobacteria the substratum becomes rich in nitrogen. Such nitrogen fixing cyanobacteria are now regularly inoculated in the rice fields This saves application of nitrogen fertilizers.

Test: Kingdom Monera (NCERT) - Question 13

Select the correct statement regarding heterocysts.

Detailed Solution for Test: Kingdom Monera (NCERT) - Question 13

Heterocyst is a large-sized pale coloured thick-walled cell which occurs in terminal, intercalary or lateral position in filamentous cyanobacteria, e.g., Nostoc. The thick wall impermeable to oxygen but permeable to nitrogen. Mucilage sheath is absent. Photosystem II is absent. Thylakoids laid phycobilisomes. Therefore, photosynthesis is absent but cyclic photophosphorylation occurs. Heterocyst is dependent for its nourishment on adjacent vegetative cells. It has enzyme nitrogenase and so, it is specialised to perform nitrogen fixation.

Test: Kingdom Monera (NCERT) - Question 14

In 5-kingdom classification system, the kingdom that includes the blue-green algae, nitrogen-fixing bacteria and methanogenic archaebacteria, is

Detailed Solution for Test: Kingdom Monera (NCERT) - Question 14

Monera kingdom includes prokaryotes - mycoplasma bacteria, actinomycetes and cyanobacteria or blue greet algae. Alongwith fungi, they are decomposers and mineralisers of the biosphere.

Test: Kingdom Monera (NCERT) - Question 15

Assertion: Prokaryotic chromosome differs from a eukaryotic one by the absence of histone proteins

Reason: Bacterial cell is a prokaryote

Detailed Solution for Test: Kingdom Monera (NCERT) - Question 15

Answer: (b)

  • In bacterial cell, a well defined membrane-bound nucleus is not found, i.e., nuclear membrane, nucleolus and chromosomes, like a typical eukaryotic cell, are absent. It contains a single chromosome, consisting of a ringed or circular DNA filament associated with a small amount of RNA and non-histone proteins.
