Question

5. If diploid chromosome number in a
flowering plant is 12, then which one of
the following will have 6 chromosomes?
a. Endosperm b. Leaf cells
c. Cotyledons
d. Synergids​

Answer 1

Answer: (d) Synergids

Explanation:

2n = 12 n = 6         ..(given)

All the diploid structures (leaf cells, cotyledons) will have 12 chromosomes.

Endosperm being triploid will have 18 chromosomes (3n=18).

Synergids are haploid structures found in the embryo sac, therefore will have 6 chromosomes.
