Question

State two functions of the pollen tube

Answer 1

They act as conduits to transport the male gamete cells from the pollen grain—either from the stigma (in flowering plants) to the ovules at the base of the pistil or directly through ovule tissue in some gymnosperms.

_______________________________________________________

The pollen tube transfers the pollen grain (male part) which has fallen on the stigma to the ovule (female part) inside the ovary through the style resulting in fertilization after the pollen fuses with the ovule

Answer 2

The pollen tube of most seed plants acts as a conduit to transport sperm cells from the pollen grain, either from the stigma (in flowering plants or angiosperms) to the ovules at the base of the pistil, or directly through ovule tissue in some gymnosperms (conifers and gnetophytes).
