Solution
The correct option is A Epistase
- A few cells of the nucellar epidermis between embryo sac and micropyle become specialized to form epistase.
- They are thick cutinized cells and often form a cap between megasporocyte and megagametophyte.
- These cells persist for a longer period of time and their function is not clearly understood.
- The group of specialized thickened nucellar cells between embryo sac and chalaza is hypostase. They provide nourishment to the growing embryo.
Thus, the correct answer is 'Epistase' .
