Question

If the cells of the nucleus in the angiosperm ovule contains $24$ chromosomes, what will be the number of chromosomes in the endosperm of a self pollinated flower?

• A. $12$
• B. $24$
• C. $36$
• D. $48$

Answer 1

The correct option is C $36$

Somatic cells of angiosperms are diploid. The ovule is diploid.

Hence 2n= 24. So n= 12.

Since the endosperm is triploid 3n = 3x12= 36.

Thus the correct answer is option C.
