Filiform apparatus is a characteristic feature of
A
Zygote
B
Suspensor
C
Egg
D
Synergid
Detailed Solution
The egg apparatus at the micropylar end of the embryo sac consists of one egg cell and two synergids.
The synergids have special cellular thickenings (finger-like projections) at the micropylar tip, called the filiform apparatus.
The filiform apparatus plays an important role in guiding the pollen tube into the synergid.
The egg, the zygote and the suspensor do not have this structure.
Hence the filiform apparatus is a characteristic feature of the synergid.
