Question

Endosperm cell of an angiosperm has $24$ chromosomes. The number of chromosomes in the gametes would be ________.

• A. $8$
• B. $16$
• C. $24$
• D. $48$

Answer 1

The correct option is A $8$

In angiosperms, endosperm is a triploid structure which is formed after double fertilisation (triple fusion). Endosperm provides nutrition to the developing embryo. Here, endosperm (3n) has 24 chromosomes, therefore n = 8. As gametes are haploid (n) structures, thus number of chromosomes in gametes will be 8.

So, the correct option is A.
