Answer 1

stem-42
primary endosperm nucleus-63
antipodal cell-21
leaf-42
zygote-42

Answer 2

Answer:

Synergids are the part of female gametophyte/embryo sac that develops from meiosis in diploid megaspore mother cell i.e., gametogenesis and hence are haploid cells. Since the diploid chromosome number (2n) for Gossypium is 52; the synergids (n) will have 26 chromosomes. Leaf cells are the diploid cells which carry the same chromosome number as is found in other somatic cells of that species.
