In a pollen grain, there were two cells, the generative cell and the tube cell. When the pollen grain lands on the pistil of a compatible flower, the generative cell undergoes mitosis to form two sperm cells while the tube cell germinates and forms the pollen tube down to the female egg.
What is the name of the process when a pollen tube is formed down to a female egg in a flower?
pollination
Reply:hehe, not a pistil- that's the actual part of the plant. I am not sure I have ever come across that term other than referring to it as part of the fertilization process. I suppose that since we would possibly call sexual intercourse "part of the process" this still counts, just slightly removed. This is similar in that the plants male (pollen grain) and female (stigma) bits get together and the actual pollen tube forming part is just how the gametes come together...
I hope that was somewhat helpful
