Answer:

Once a pollen grain has implanted on a compatible stigma via self-incompatibility mechanisms, the germination process is initiated. During this process, the pollen grain undergoes a conformational change whereupon a given section begins to protrude outwards to form a tube-like structure, known as the pollen tube.
