Meaning of "pollen tube"
A pollen tube is a tubular structure formed by a pollen grain that grows towards the ovule of a flower during pollination. It carries the male gametes to the female reproductive organs, allowing fertilization to occur
Show more definitions
- the tube that develops from the wall of a pollen grain and, in seed plants, provides a passage through which the male nuclei reach the embryo sac to effect fertilization
