Pollination is a method by which pollen grains are picked from the anther, which is the male part of the flower, and transferred to the female part of the flower called the stigma. The pollination process begins when the pollen grains of the respective flowers land on the stigma and form a pollen tube using the style length that connects the stigma and the ovaries. After the pollen tube is finished, the pollen grains transmit the sperm cells from the grain to the ovaries.
Later, the fertilisation process takes place when the sperm cells reach the ovaries and the egg cells. The seed is then released from the parent plant, allowing it to grow into a plant and continue the reproductive cycle using the pollination method.
Types of Pollination
All plants with flowers rely entirely on the method of pollination for reproduction. There are two types of pollination, namely self- and cross-pollination.
- Self-pollination: It is the primary type as it involves a single flower. Self-pollination occurs when pollen grains fall directly from the anther into the flower stigma.
- Cross-pollination: It is a complex form of pollination that allows pollen grains to be transferred from the anther of the flower to the stigma of another flower.
