Question
State the function of the pollen tube.
Answer
A pollen tube is a slender, tube-like structure that develops from a pollen grain after it has landed on a stigma (the receptive part of a flower's female reproductive organ). Pollen tubes play a crucial role in the process of fertilization in flowering plants.
The functions of the pollen tube include:
1. Secretes enzymes that digest the stigma/style/ovary tissue
2. Offer passage for male nuclei to ovum and polar nucleus/embryo sac
