Question

Nuclear dna consists of 46 chromosomes whereas mitochondria dna consists of only one chromosome

Answer 1

Explanation:

The embryo sac contains 32 chromosomes and 8 haploid nuclei, so each nucleus must contain 4 chromosomes. Therefore the egg cell has 4 chromosomes, the synergid cell has 4 chromosomes, etc. The endosperm mother cell has two polar nuclei so it contains a total of 8 chromosomes.
