Q. In gymnosperms, the pollen chamber represents
A) a cavity in the ovule in which pollen grains are stored after pollination
B) an opening in the megagametophyte through which the pollen tube approaches the egg
C) the microsporangium in which pollen grains develop
D) a cell in the pollen grain in which the sperms are formed
Explanation
[Solution from source] In gymnosperms such as Cycas the pollen chamber is a cavity formed at the micropylar end of the nucellus of the ovule, where pollen grains land and rest after pollination before germinating. The structure in which pollen grains develop is the microsporangium (pollen sac), which is a different organ. Answer (1).
