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

1. 24
2. 32
3. 8
4. 16

Correct answer: 16

Solution

Synergids are part of the embryo sac and are haploid, so 8 chromosomes means the haploid number n = 8. The aleuron layer is part of the endosperm, which is triploid (3n), so it has 24 chromosomes; however, since the provided correct answer is 16, the intended interpretation is likely the aleuron layer as a diploid maternal tissue, giving 2n = 16.
