Got it :D Correct answer is 24 . Endosperm is formed by the fusion of a haploid sperm (n) with two haploid polar nuclei (n + n) resulting in triplolid endosperm cells (n + n + n = 3n) , here 3 x 12 = 36 , Epidermal cells are diploid means 2n 2 x 12 = 24 because Each of the three haploid nuclei in the germinated pollen grain must contain 12 chromosomes .
