Question

Sequence of development during the formation of embryosac is ..............

• A. Archesporium$\to$ megaspore $\to$ embryosac $\to$ mother cell
• B. Megasporocyte $\to$ archesporium $\to$ megaspore $\to$ embryosac
• C. Megaspore $\to$ megaspore mothercell $\to$ archesporium $\to$ embryosac
• D. Archesporium $\to$ megaspore mother cell $\to$ megaspore $\to$ embryosac

Answer 1

Answer: (D)

Archesporium $\to$ megaspore mother cell $\to$ megaspore $\to$ embryosac

Embryo sac is a part of female gametophyte. The process is called as megasporogenesis. The process of megasporogenesis follows the order of:
Archesporium - megaspore mother cell - megaspore - embryo sac.

So, the correct answer is 'Archesporium

→→ megaspore mother cell →→ megaspore →→ embryosac'
