NEET Biology QUESTION #7253
Question 1
In gymnosperms, the pollen chamber represents:
  • The microsporangium in which pollen grains develop
  • A cell in the pollen grain in which the sperms are formed
  • A cavity in the ovule in which pollen grains are stored after pollination✔️
  • An opening in the megagametophyte through which the pollen tube approaches the egg
Correct Answer Explanation
The pollen chamber in gymnosperms is a cavity formed in the nucellus of the ovule where pollen grains are deposited after pollination. It is a temporary chamber that forms by degeneration of nucellar cells near the micropyle. From here, pollen grains germinate and the tube grows toward the archegonia.
