Pollen tube enters the embryo sac usually

Options

A. Through one of the synergids
B. By directly penetrating the eggs
C. Between one synergid and central cell
D. By knocking off the antipodal cells.

Answer

A

Explanation

After entering the wall of the embryo sac the pollen tube during its entry into the embryo sac passes through the nucellar cells and the synergids,e.g. Fagopyrum.The pollen tubes passes between the egg and one synergid.In cardiospermum,it passes between embryo sac wall and syergrid.In Oxalis,it passes directly through a synergid.In Viola it enrers a synergid and makes its way through the base of the synergid.In normal pollen tube and the other remains intact untill sometimes afterwards.
