Endosperm Development & Coconut Water — NEET Biology

✅ Asked in NEET 2016
📖 NCERT Source

The cells of this tissue are filled with reserve food materials and are used for the nutrition of the developing embryo. In the most common type of endosperm development, the PEN undergoes successive nuclear divisions to give rise to free nuclei. This stage of endosperm development is called free-nuclear endosperm. Subsequently cell wall formation occurs and the endosperm becomes cellular. The number of free nuclei formed before cellularisation varies greatly. The coconut water from tender coconut that you are familiar with, is nothing but free-nuclear endosperm (made up of thousands of nuclei) and the surrounding white kernel is the cellular endosperm.

How NTA Uses This Concept

NTA tests whether students know that coconut water is free-nuclear endosperm (containing thousands of free nuclei without cell walls), while the white kernel is cellular endosperm (with cell walls formed after cellularisation). The trap: students confuse coconut water with the embryo or think the white part is free-nuclear. The concept appears in NEET 2016 and tests understanding of endosperm development stages—first free-nuclear (PEN divisions without cell walls), then cellular (after wall formation). Remember: coconut water = thousands of free nuclei; white kernel = cellular tissue. This distinguishes endosperm types and nutritive functions in flowering plants.
