Question

In Angiosperms pollen tube liberate their male gametes into the : -

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

Answer 1

The correct option is D Synergids

The contents of the pollen tube are discharged in the synergid from where the first male gamete is transferred to the egg cell, while the other male gamete moves to the central cell through cytoplasmic current. On reaching of pollen tube inside the embryo sac, the 2 male gametes are discharged through a subterminal pore in the pollen tube. The contents of the pollen tube are discharged in the synergid and the pollen tube does not grow beyond it in the embryo sac. Further, the cytoplasm of the pollen tube is restricted to the chalazal end of this synergid cell.

So, the correct answer is 'Synergids'.
