Question

What is the function of filiform apparatus in an angiospermic embryo sac?

• A. Guides pollen tube from synergid to egg
• B. Helps in the entry of more than one pollen tube into a synergid
• C. Prevents entry of more than one pollen tube into a synergid
• D. Brings about opening of the pollen tube.

Answer 1

The correct option is A Guides pollen tube from synergid to egg

The function of filiform apparatus in an angiospermic embryo sac is to guide the entry of pollen tube from synergid to egg. The synergid cells present within the female gametophyte play a vital role in the reproduction process in angiosperm. The cell wall of synergid develops an extremely thick structure called the filiform apparatus at the micropylar end of the ovule.

So, the correct answer is 'Guides pollen tube from synergid to egg'.
