Question

The pollen tube usually enters the embryo sac:

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

Answer 1

The correct option is A Through one of the synergids

Pollen tube enters the embryo sac through one of the synergid cells as it provides direction to the polar nuclei for triple fusion. The synergids of the embryo sac literally put their energies together to burst the end of the pollen tube.

So, the correct answer is option A.
