Full Answer

The stigma is contained inside of the pistil, which also contains the ovary, style and carpel. A pistil may have several carpels. The style is the part of the flower, also called a stalk, that allows pollen tubes to grow from grain. These tubes become part of the stigma and helps it to receive the pollen. The carpel and its other parts can often be referred to as the gynoecium, a Greek word meaning "woman's house."

  • Q:

    What is the difference between pollination and fertilization?

    A:

    Pollination is the process whereby pollen grains move from the anther to the stigma on a flower’s style, while fertilization is the fusion of the male gametes and female egg cells to form a new plant seed. Pollination precedes fertilization and depends on such media as wind, water and insects. Pollination takes place externally, while fertilization occurs in the inside of the flower and does not depend on external vectors.
