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 approches the egg
4 The microsporangium in which pollen grains develop
Explanation:
In gymnosperms, the pollen chamber is acavity in the ovule in which pollen grains are stored after pollination. Within this chamber, the generative cell divides to form two male gametes and the pollen cell starts elongating to form pollen tube.

What is the similarity between gymnosperms and angiosperms?
1 Phloem of both have companian cells.
2 Endosperm is formed before fertilization in both.
3 Origin of ovule and seed is similar in both.
4 Both have leaves, stem and roots.
Explanation:
Gymnosperms (including conifers) and angiosperms both have advanced support tissues true leaves, stems and roots they also are the two groups that produce pollen and seeds.
