The endosperm, a triploid tissue (3n) with 30 chromosomes, develops from the fusion of one sperm nucleus and two polar nuclei. Concurrently, the diploid zygote (2n) with 20 chromosomes is formed by the fertilization of the egg cell by another sperm nucleus. This double fertilization mechanism, characteristic of angiosperms, guarantees embryo development and the creation of nutrient-rich endosperm for seed sustenance, crucial for germination and plant proliferation.% Quick tip
