Question

In embryo sac, which one commonly develops haustoria

• A. Synergids
• B. Antipodal cells
• C. Oosphere
• D. Central cell

Answer 1

The correct option is B Antipodal cells

Haustorium is a projection or outgrowth that can penetrate other tissues to absorb nutrients. Both synergids and antipodals cells may develop haustoria in the embryo sac but the haustorial behavior of antipodal cells is known in many plants. Moreover, antipodal cells have a nutritive function as they provide nutrients for the embryo sac. Hence, developing haustoria will aid in nutrient absorption from the nearby tissues. Thus, in an embryo sac, haustoria are commonly developed by the antipodal cells.

So, the correct answer is B.
