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 |
