One of the major compounds of the cell wall of most fungi is:
1. | peptidoglycan | 2. | cellulose |
3. | hemicelluloses | 4. | chitin |
T.O. Diener discovered a
1. | free infectious RNA | 2. | free infectious DNA |
3. | infectious protein | 4. | bacteriophage |
Both Archaebacteria and Eubacteria:
I: | have a similar structure of cell wall |
II: | are members of Kingdom Monera |
1. Only I is correct
2. Only II is correct
3. Both I and II are correct
4. Both I and II are incorrect
I: | has non-cellulosic cell wall composed of polysaccharide and amino acids |
II: | has a nuclear membrane but it is not double layered |
Assertion (A): | Amoeba and Paramoecium are included in Kingdom Protista and not in Kingdom Animalia. |
Reason (R): | Unlike animals, a cell wall is present in these organisms. |
1. | Both (A) and (R) are True but (R) does not correctly explain (A). |
2. | (A) is False but (R) is True. |
3. | Both (A) and (R) are True and (R) correctly explains (A). |
4. | (A) is True but (R) is False. |
I: | Bacteria and blue green algae have prokaryotic cell organization unlike other members included in ‘plants’. |
II: | Fungi and many bacteria are heterotrophic unlike autotrophic members included in ‘plants’. |
1. | Virus | 2. | Viroid |
3. | Prion | 4. | Bacterium |
1. | Diatoms | 2. | Dinoflagellates |
3. | Euglenoids | 4. | Blue green algae |
