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 |

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 |
