What would be the number of chromosomes in the cells of the aleurone layer in a plant species with 8 chromosomes in its synergids?

  • 16

  • 24

  • 32

  • 8

Answer

B.

24

Synergids are two, short-lived, haploid cells lying close to the egg in nature embryosac of flowering plant ovule. While the endosperm is a triploid tissue formed after triple fusion. Thus, if the synergids have 8 chromosomes, the aleurone layer (part of endosperm) will have just triple of that of chromosomes in the synergids i.e, 24 chromosomes.
