Question

Through which cell of the embryo sac, does the pollen tube enter the embryo sac?

Egg cell

Central cell

Persistant synergid

Degenerated synergid

Solution

Degenerated synergid

Egg apparatus is present towards the micropylar end of an ovule. It has two lateral synergid cells and one centrally located egg cell. During entry of pollen tube within the ovule, synergid cells become disintegrate and provide path for entry of pollen tube within the chamber of embryo sac.
