What is the function of filiform apparatus in an angiospermic embryo sac ? |
Provide protection to the egg. Helps in the formation of pollen tube. Guides the pollen tube into a synergid . Helps in the opening of pollen tube. |
Guides the pollen tube into a synergid . |
The correct answer is Option (3)- Guides the pollen tube into a synergid . Filiform apparatus refers to the specialized cellular thickenings found at the micropylar tip of the synergid cells in the embryo sac of angiosperms. The filiform apparatus helps guide the pollen tube towards the synergid cells, allowing for the delivery of the male gametes (sperm cells) to the vicinity of the egg cell for fertilization to occur. The filiform apparatus provides a physical pathway and may also be involved in the secretion of attractants or guidance cues for the pollen tube.
