NEET · Biology · STD 12 - 1. sexual reproduction in flowering plants
Megaspores are produced from the megaspore mother cells after
- A mitotic division
- B formation of thick wall
- C differentiation
- D meiotic division.
Answer & Solution
Correct Answer
(D) meiotic division.
Step-by-step Solution
Detailed explanation
(d) : In angiosperms, microsporogenesis \(i.e.\),formation of microspores (or pollen grains) occurs by the meiotic divisions of diploid microspore mother cells (or pollen mother cells).Microsporogenesis takes place in the anther. Megasporogenesis \(i.e.\) formation of megaspores occurs by the meiotic divisions of diploid megaspore mother cells. Megasporogenesis takes place in the ovule.
