Question

In angiosperms, pollen tube liberates their, male gametes into the ______.

Options

• central cell 

• antipodal cell 

• egg cell 

• synergids

Answer 1

In angiosperms, pollen tube liberates their, male gametes into the synergids.

Explanation:

The synergid, where the first male gamete is transmitted to the egg cell and the other male gamete travels to the central cell through cytoplasmic current, receives the discharge of the pollen tube's contents. The two male gametes are released by a subterminal pore when the pollen tube is reached inside the embryo sac. The pollen tube's contents are expelled in the synergid, and the pollen tube doesn't develop further in the embryo sac after that. Furthermore, only the chalazal end of this synergid cell has pollen tube cytoplasm.
