Q. Through which cell of the embryo sac, does the pollen tube enter the embryo sac ?
A) Egg cell
B) Central cell
C) Persistant synergid
D) Degenerated synergid
Explanation
[Solution from source] The pollen tube, guided by the filiform apparatus, enters one of the synergids, which degenerates and releases the male gametes. The other, persistent synergid is not entered, and the tube does not go directly into the egg or the central cell. Answer (4).
