The terms ‘bracket fungi’ or ‘pufballs’ is used for some of the members of the class:
1. Phycomycetes
2. Ascomycetes
3. Basidiomycetes
4. Deuteromycetes
Chemosynthestic autotrophic bacteria:
| I. | Produce ATP by oxidizing inorganic substances |
| II. | Play a great role in recycling nutrients like nitrogen, phosphorus, iron and sulfur |
| 1. | Both I and II are correct | 2. | Only I is correct |
| 3. | Only II is correct | 4. | Both I and II are incorrect |
Identify the incorrect statement regarding true bacteria?
| 1. | As a group, they exhibit maximum metabolic diversity. |
| 2. | Chemosynthetic autotrophic bacteria play a great role in recycling nutrients like nitrogen, phosphorous, iron and sulphur. |
| 3. | Heterotrophic bacteria are the most abundant in nature. |
| 4. | Bacteria reproduce mainly by fission but sometimes under favourable conditions, they produce spores. |
In Whittaker’s Five Kingdom classification, heterotrophic mode of nutrition is present in members of:
| 1. | Two kingdoms | 2. | Three kingdoms |
| 3. | Four kingdoms | 4. | Five kingdoms |

All the following are correct regarding mycoplasma except:
1. they lack a cell wall
2. they are obligate aerobes
3. they are smallest living cells known
4. many are pathogenic in plants and animals
Which of the following would best describe a virus?
| 1. | Non cellular organization, crystalline inert structure in a living cell |
