Question

In gymnosperms, the pollen chamber represents

• A. A cavity in the ovule in which pollen grains are stored.
• B. An opening in the megametophyte through which the pollen tube approaches the egg
• C. The microsporangium in which pollen grain develops
• D. A cell in the pollen grain in which the sperms are formed

Answer 1

The correct option is A A cavity in the ovule in which pollen grains are stored.

The pollen chamber is formed by degeneration of cells of nucellus situated in the micropylar part. It is a pre-pollination phenomenon and should be distinguished from degeneration of nucellar cells in its micropylar part following landing of pollen on nucellus or entry of pollen tube in the nucellus. It is where the pollens are stored.

Hence the correct option is A.
