Name the parts A, B and C of the diagram given below. Write a function of the part B.

A is the pollen grain, B the pollen tube and C the female germ-cell; the pollen tube carries the male germ-cell to the egg.
A - Pollen grain; B - Pollen tube; C - Female germ-cell (the egg cell) inside the ovule.
