In an angiosperm seed, what is the function and ploidy of endosperm?
Answer
In an angiosperm seed, the endosperm functions as the primary nutrient source for the developing embryo. It is triploid, meaning it has three sets of chromosomes, a result of the fusion of two polar nuclei with one sperm cell during fertilization. This triploid nature allows the endosperm to have a more complex and larger genetic makeup, enabling it to store a diverse range of nutrients required for seedling growth. The endosperm’s role is critical for the successful germination and early growth of the seedling.
