Liquid endosperm in coconut is formed because of which cellular phenomenon?
Answer and explanation
Correct answer: D. Repeated free-nuclear divisions (karyokinesis) without cytokinesis
- Step 1: After double fertilization, the primary endosperm nucleus () undergoes nuclear division.
- Step 2: In free-nuclear endosperm development, successive rounds of karyokinesis are not accompanied by cytokinesis.
- Step 3: This produces a liquid syncytium containing thousands of free nuclei suspended in watery fluid, as seen in green coconut water.
Answer
Repeated free-nuclear divisions (karyokinesis) without cytokinesis.
Why not the others: Meiotic non-disjunction produces aneuploid gametes, not endosperm syncytium; Excessive deposition of cell plates would produce hard solid cellular endosperm; Apomictic development describes asexual seed production without fertilization.
