If the seed in the picture above is a gymnosperm seed, identify whether each of the labeled structures is haploid, diploid, or triploid 1. Diploid The structure labelled \'A\' 2. Haploid The structure labelled \'B\' 3 Triploid The structure labelled \'C\' The structure labelled \'D\'

Solution

Answer:

Structure A - Outer seed coat - Diploid

Structure B - Inner seed coat - Diploid

Structure C - Endosperm - Haploid

Structure D - Embryo - Diploid

Double fertilization does not occur in gymnosperm, in which the endosperm is haploid (n) tissue for the same genotype as the unfertilized egg cell.

Thus gymnosperm seeds contain a mixture of three genetically different type of tissue:
