Question

What would be the number of chromosomes in the megaspore mother cell of the plant if an endosperm of an angiosperm has 24 chromosomes?

Options

• 4

• 16

• 20

• 24

Answer 1

16

Explanation:

An endosperm is triploid, while a megaspore mother cell is diploid. Endosperm (3n) = 24

∴ n = 8

megaspore mother cell = 2n = 2 x 8 = 16
