Endosperm Development & Primary Endosperm — NEET Biology
✅ Asked in NEET 2026Endosperm development precedes embryo development. Why? The primary endosperm cell divides repeatedly and forms a triploid
The primary endosperm cell (formed by fusion of polar nuclei and one sperm nucleus) divides repeatedly to form the triploid endosperm tissue before embryo development. This happens because endosperm provides nutritive support needed for embryo growth. Students often confuse whether endosperm or embryo develops first, or mix up the ploidy level (3n vs 2n). Remember: endosperm is 3n and develops faster to create a nutrient reserve; embryo (2n) develops slower. NEET tests this to check if you understand double fertilization consequences and nutritional coordination in seed development.
Which one of the following is a triploid cell?
