What does the filiform apparatus do at entrance into ovule?

Options:
A It helps in the entry of pollen tube into synergid
B It prevents entry of more than one poll tube into the embryo sac
C It brings about opening of the pollen tut
D It guides pollen tube from a synergid to $\mathrm{e}$

The correct answer is:
It helps in the entry of pollen tube into synergid

Solution:
In most cases the mature embryo sac contains 7-cells and 8-nuclei. The cells are arranged as egg apparatus (two synergid cell and one egg cell), a central cell with two nuclei and antipodal cells (3 in number). The synergid cells occur laterally to the egg cell. These cells are characterised by finger-like projections called filiform apparatus towards the micropylar end. Filiform apparatus is formed due to invaginations of cell wall into the protoplasm and is made up of pectocellulosic fibres evolved in non-cellulosic sheath. Secretion of chemotactic substances for the attraction of pollen tube during fertilization is the function of synergids. One synergid becomes degenerate during pollen entry into the embryo sac and thus, provides a way for entry of pollen tube into the embryo sac.

Topic: Biology, Sexual Reproduction in Flowering Plants, NEET, NEET 2008 (Screening)
What does the filiform apparatus do at the entrance of the ovule?

Options:
A It brings about opening of the pollen tube.
B It helps in the entry of pollen tube into a synergid.
C It prevents entry of more than one pollen tube into the embryo sac.
D It guides pollen tube from a synergid to egg.

The correct answer is:
It helps in the entry of pollen tube into a synergid.

Solution:
Within the embryo sac, three cells are grouped together at the micropylar end and constitute the egg apparatus. The egg apparatus, in turn, consists of two synergids and one egg cell. The synergids have special cellular thickenings at the micropylar tip called filiform apparatus, which plays an important role in guiding the pollen tubes into the synergid. Three cells are at the chalazal end and are called the antipodals. The large central cell has two polar nuclei.
