Answer:
The function of the pollen tube is to lead sperm cells into the ovary.
Explanation:
In angiosperms, the pollen tube is a structure formed when the pollen grain comes into contact with the stigma and germinates, producing a tubal extension that is related to the embryonic sac where the female gametophyte is found.
The function of the pollen tube is to conduct the male gametophyte —which is found in the pollen— to the embryonic sac, in order to come into contact with the oosphere and produce fertilization.
The other options are not correct because the pollen tube:
- <em>Do </em><u><em>not create more pollen</em></u><em>.
</em>
- <em>Do </em><u><em>not create more male spermatophytes</em></u><em>.
</em>
- <u><em>Does not lead the eggs to the male spermatophytes</em></u><em>.</em>

Although all cells have the same DNA only some parts of it are turned on depending on what the cell needs to do, so each cell turns on different parts of itself depending on what its job is.
Hope this helps!
