Which of the following is incorrect in angiosperm?

Pollen grain - Haploid

Megaspore - Diploid

Synergid - Haploid

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.
