Question

13. Assertion: Endosperm is formed by the fusion of one male gamete and two polar nuclei.
Reason: In
pea, the endosperm remains the part of seed as it is not completely consumed
up during embryo formation.​

Answer 1

Answer 2

Both the statements of assertions and reasons are correct but the reason is not the correct explanation for the assertion.

• In plants, fertilization is a sexual process in which the male gamete fuses with the female gamete to form a diploid zygote.
• Double fertilization is a characteristic of flowering plants in which a female gametophyte fuses with two male gametophytes.
• In this process, one sperm cell fuses with the egg and the other fuses with the polar nuclei to form endosperm.
• Whereas the reason states that in peas the endosperm retains even after embryo formation this is because pea is an albuminous type of seed which means the endosperm is not completely consumed after embryo formation.
• There both the assertions and reactions are correct but the reason does not explain the assertion.
