1. | Majority of them are marine water organisms found in running water. |
2. | The cell wall has stiff cellulose plates on the outer surface. |
3. | They have only one flagellum. |
4. | Though they are photosynthetic in the presence of sunlight, when deprived of sunlight they behave like heterotrophs. |
1. | Heterotrophic mode of nutrition |
2. | Sexual stage is unknown |
3. | Lack of vegetative reproduction |
4. | Called as bracket fungi |

1. | They have chlorophyll a (similar to green plants) |
2. | They are unicellular and never colonial or filamentous |
3. | They often form blooms in polluted water bodies |
4. | Some of them can fix atmospheric nitrogen |
The chief ‘producers’ in the oceans are:
1. Cyanobacteria
2. Dinoflagellates
3. Diatoms
4. Lichens
Slime molds:
1. | form plasmodium that differentiates and forms fruiting bodies bearing spores at their tips during unfavourable conditions. |
2. | form plasmodium that differentiates and forms fruiting bodies bearing spores at their tips during favourable conditions. |
3. | form plasmodium under favourable conditions and the plasmodium differentiates and forms fruiting bodies bearing spores at their tips during unfavourable conditions. |
4. | form plasmodium under unfavourable conditions and the plasmodium differentiates and forms fruiting bodies bearing spores at their tips during favourable conditions. |
In the five kingdom classification, the members of Kingdom Animalia:
I: | are all heterotrophs |
II: | are all multicellular where cells lack a cell wall |
1. Only I is correct
2. Only II is correct
3. Both I and II are correct
4. Both I and II are incorrect
