In the life cycle of a moss, the sporphytic generation is represented by all the following except:
| 1. | Oospore | 2. | Spore |
| 3. | Sporogonium | 4. | Spore mother cell |
A species of red algae has been discovered near Bahamas at a depth of more than 260 m. This unusual feat is possible because this alga:
| 1. | lacks pigmentation and functions heterotrophically as parasite on other plants |
| 2. | has significant amount of phycoerythrin in addition to chlorophyll a and d |
| 3. | unlike other red algae has flagellated gametes |
| 4. | it has large number of root like rhizoids enabling it to attach to a deep substratum |
Identify the incorrect statement:
| 1. | As compared to the bryophytes, pteridophytes have sporophyte as the main plant body |
| 2. | Pteridophyte sporophyte has well differentiated true roots, stem and leaves |
| 3. | Selaginella has macrophylls like ferns |
| 4. | In sporophyte of ferns, leaf-like appendages called sporophylls subtend sporangia |
All the following regarding Pinus are correct except:
1. Obligate association with mycorrhiza
2. Unbranched stems
3. Male and female strobili on the same plant
4. Leaves in fascicles
Coralloid roots in Cycas are associated with nitrogen fixing:
| 1. | Rhizobium | 2. | Frankia |
| 3. | Azospirillum | 4. | Cyanobacteria |
In gymnosperms, the ovules are:
| 1. | not enclosed by any ovary wall before and after fertilization |
| 2. | not enclosed by any ovary wall only before fertilization |
| 3. | not enclosed by any ovary wall only after fertilization |
| 4. | enclosed by an ovary wall before and after fertilization |
Consider the following two statements:
| I: | In Selaginella and Salvia, development of zygotes into young embryos takes place within the female gametophyte. |
| II: | Selaginella and Salvia are homosporous pteridophytes |
1. Both I and II are correct and II explains I
2. Both I and II are correct but II does not explain I
3. I is true but II is false
4. I is false but II is true
Consider the following two statements:
| I: | The spread of living pteridophytes is restricted to narrow geographical regions |
| II: | They are the first terrestrial plants to possess vascular tissues |
1. Both I and II are correct and II explains I
2. Both I and II are correct but II does not explain I
3. I is true but II is false
4. I is false but II is true
The given diagram shows:
1. Female thallus of Marchantia
