A) Sperm B) Antipodal C) Egg D) Synergid

Answer 1

D) Synergids

Answer 2

Filiform apparatus is found in synergids.

So, the correct option is (D)

In the ovule, the female gametophyte, that is, the embryo sac is present. Inside the embryo sac, three antipodal cells, two synergids a central polar nuclei and an egg is present.

Inside the synergids, filiform apparatus is present. This structure has the function to guide the pollen tube to enter through the synergids.

As soon as the pollen tube enters the embryo sac, the degeneration of synergids occurs.
