Question

Identify the correct sequence of cells formed during embryo sac development.

• A. Megaspore mother cell - Megaspore tetrad - Embryo Sac- Nucellus
• B. Megaspore mother cell - Megaspore tetrad - Functional megaspore - Embryo Sac
• C. Sporogenous cell - Megaspore tetrad- Megaspore mother cell - Embryo Sac
• D. Nucellus - Sporogenous cell - Embryo Sac - Megaspore-Megaspore mother cell

Answer 1

The correct option is B

Megaspore mother cell - Megaspore tetrad - Functional megaspore - Embryo Sac

From nucellus, one megaspore mother cell undergoes differentiation to form megaspore tetrad. Out of 4 megaspores, one acts as functional megaspore. This will develop into embryo sac.
