In agamospermy, diploid embryo sac is derived from

Options

A. Megaspore without meiosis
B. Microspore
C. Megaspore mother cell without meiosis
D. Microspore mother cell without meiosis

Answer

C

Explanation

In agamospermy a diploid embryo sac is formed either from the diploid nucellar cells (a phenomenon called apospory) e.g. citrus, mango etc. or from the diploid megaspore mother cell a phenomenon called diplospory. In such embryo sac the egg and all other cells are diploid. The diploid egg develops parthenogenetically without the act of fertilisation.
