Answer 1

The pollen tube usually enters the embryo sac between the egg cell and synergid.

Explanation:

Usually, one of the synergids allows a pollen tube to enter the embryo sac. It enters one of the synergids through the filiform apparatus. The egg apparatus, which comprises one egg cell and two surrounding cells, is located at the micropylar end of the eight nucleate female gametophytes of flowering plants.
