1. Curing high blood pressure
2. Kidney failure
3. Eye defect
4. Diabetes
In gymnosperms, the pollen chamber represents:
| 1. | a cell in the pollen grain in which the sperms are formed |
| 2. | a cavity in the ovule in which pollen grains are stored after pollination |
| 3. | an opening in the megagametophyte through which the pollen tube approaches the egg |
| 4. | the microsporangium in which pollen grain develop |
1. Curing high blood pressure

1. Funaria and Ficus
2. Fern and Funaria
3. Funaria and Pinus
4. Ficus and Chlamydomonas
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.
From an evolutionary point of view, retention of the female gametophyte with developing young embryo on the parent sporophyte for some time, is first observed in:
| 1. | Gymnosperms | 2. | Liverworts |
| 3. | Mosses | 4. | Pteridophytes |
