What is filiform apparatus give its function?

A filiform apparatus’ function is to guide pollen tubes’ entry, extract food from the nucleus, and help metabolites at short distances. The filiform apparatus is a finger-like projection, a highly thickened structure formed from synergid cell walls at the micropylar.

Where are filiform apparatus?

The filiform apparatus is the thickened and prominent structure present in the synergids cells of the embryo sac. They are the finger-like projections that are located near the micropylar end of the embryo sac.

What is the function of filiform apparatus in a angiosperm embryo sac?

Option B: Filiform apparatus is an apparatus that is formed inside the embryo sac of the angiosperms by the synergid cells. This apparatus helps the pollen tube towards the egg for fertilization to happen. Thus it helps in the reproduction process of the angiospermic plants.

What is the function of filiform apparatus in an angiosperm embryo sac?

What is the role of filiform apparatus in embryo sac?

Option B: Filiform apparatus is an apparatus that is formed inside the embryo sac of the angiosperms by the synergid cells. This apparatus helps the pollen tube towards the egg for fertilization to happen. The role of the filiform apparatus is to allow the entry of pollen tubes from the synergids to the egg.

Is filiform apparatus a part of egg apparatus?

No, Egg apparatus and filiform apparatus are not same. In embryo sac, the egg apparatus present in the micropylar end consists of two synergids and one egg cell.

What is the main function of filiform apparatus present at the micropylar part of the ovule?

Answer (e) It guides the entry of pollen tube into a synergid and discharge the male gametes.
