Question

If the nucellus cell of an Angiosperm contains $24$ chromosomes the number of chromosomes present in pollen grain, endosperm & embryo will be?

• A. $24,36,24$
• B. $12,36,24$
• C. $12,24,36$
• D. $24,12,12$

Answer 1

The correct option is C $12,24,36$

Nuclellus is a part of sporophyte so they are diploid cells and their ploidy is 2n. Hence, n = 12.

Pollen grain is haploid, n = 12.

Endosperm is Triploid, 3n = 36.

Embryo Sac is diploid, 2n = 24.

So, the correct option is '12, 36, 24'.
