Question

What does the filiform apparatus do at the
entrance into ovule?
(a) It brings about opening of the pollen tube
(b) It guides pollen tube from a synergid to egg
(c) It helps in the entry of pollen tube into a
synergid
(d) It prevents entry of more than one pollen
tube into the embryo sac

Answer 1

Filiform apparatus is defined as the prolongation of the synergids beyond the summit of the embryo sac. The function of the filiform apparatus is that it helps in leading the pollen tubes in the synergids. This is an important process during fertilization in the angiosperms. 

Thus, the correct answer is option C.
