1.Sexual Reproduction in Flowering Plants
medium
Which of the following is incorrect in angiosperm?
A
Pollen grain - Haploid
B
Megaspore - Diploid
C
Synergid - Haploid
D
Endosperm - Triploid
Solution
In angiosperm, a single diploid Megaspore Mother Cell (MMC) matures within an ovule. Through first meiosis, it gives rise to a dyad cell and then second meiosis takes place which forms four megaspores (haploid). In most plants, only one of these megaspore, survives, the rest are absorbed by the ovule.
