Question

Filiform apparatus is found in:

• A. Antipodal cell
• B. Egg cell
• C. Secondary nucleus
• D. Synergids

Hint:

Remember the 7-celled, 8-nucleate structure of the Polygonum-type embryo sac.
The "Egg Apparatus" at the micropylar end consists of 3 cells (1 Egg cell + 2 Synergids).
Only the synergids contain the filiform apparatus, which is essential for guiding the pollen tube.

The Correct Option is D

Step 1: Filiform apparatus.
This is a finger-like wall ingrowth in synergid cells of the female gametophyte (embryo sac). It guides the pollen tube to the egg cell.
Answer: Synergids
