Question

Function of synergids is to

• A. Attract pollen tube and bear its shock
• B. Fuse with extra male gametes and form endosperm
• C. Produce additional embryo
• D. Protect egg from pathogens

Answer 1

The correct option is A Attract pollen tube and bear its shock

Synergids are generally two in number and are present laterally to the egg cell. These cells are characterized by finger like projections called filiform apparatus present towards the micropylar end and is formed due to finger like invaginations of cell wall into the protoplasm.

Functions of synergids are:

1. They secrete chemotactic substances that attract the pollen tube during fertilisation.

2. One of the two synergids degenerate and provide a way for the entry of pollen tube in the embryo sac.

3. These act as shock absorbers during the entry of pollen tube in the embryo sac.

So, the correct answer is A.
