Question

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

Options

A.24
B.32
C.8
D.16

Solution

Synergids are two, short-lived, haploid cells lying close to the egg in mature embryo sac 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 chromosomes in the synergids ie, 24 chromosomes.
