Question

Give reasons why endosperm in angiosperms becomes triploid.

Open in App

Solution

Endosperm is formed during the double fertilization. It is triploid because it is formed when one of the two sperm that is haploid enters inside the embryo sac & fuses with two polar nuclei (each polar nuclei is haploid). So the endosperm formed is triploid.
