Pinus seeds cannot germinate and establish without fungal association. This is because:
1. its seeds contain inhibitors that prevent germination.
2. its embryo is immature.
3. it has an obligate association with mycorrhizae.
4. it has a very hard seed coat.
In which of the following gametophyte is not independent free-living?
| 1. | Funaria | 2. | Marchantia |
| 3. | Pteris | 4. | Pinus |
Which of the following statements is incorrect about gymnosperms?
1. They are heterosporous
2. Male and female gametophytes are free-living
3. Most of them have narrow leaves with thick cuticles
4. Their seeds are not covered
| 1. | ovules surrounded by integuments |
| 2. | microspores and megaspores |
| 3. | vascular tissues |
| 4. | a large, nutritionally independent gametophyte |
| Assertion (A): | In gymnosperms, the pollen grains are released from the microsporangium and carried by air currents. |
| Reason (R): | Air currents carry the pollen grains to the mouth of the archegonia where the male gametes are discharged and pollen tube is not formed. |
