Question

The cell with filiform apparatus is present towards the __(a)____end of the embryo sac and it_____(b)__________after fertilisation.

• A. a - chalazal, b - degenerates
• B. a - micropylar, b - forms endosperm
• C. a - micropylar, b - degenerates
• D. a - chalazal, b - forms endosperm

Answer 1

The correct option is C a - micropylar, b - degenerates

Filiform apparatus are cellular thickenings in the synergids. They guide the pollen tube towards the synergids. Due to this the pollen tube enters the synergids and releases the male gametes into the embryo sac.

Synergids are located at the micropylar end of the embryo sac.

They degenerate after fertilisation.
