If the diploid number of an angiospermic plant is 24, the number of chromosomes in pollen grain, endosperm and integument will be

The correct option is D 12, 36, 24

The diploid number of the angiospermic plant is 24. So, as 2n=24, n=12. Pollen grains are haploid. Hence, the number of chromosomes in pollen grains will be 12. Endosperm is triploid, so it will have 3n=36 chromosomes and integument is diploid in nature so the number of chromosomes will be 2n=24 .
