(Diagram of Flower is Attached)

The process in which the pollen grains is transferred from the anther of one flower to the stigma of the same or another flower is known as pollination. It is known to be sexual mode of reproduction in plants. There are two types of pollination. They are →

• Self Pollination → When the pollen grains of the anther is transferred to the stigma of the same flower, it is known as self pollination.

3. Vitamin A
4. Minerals

(II)Draw a neatly labeled diagram of the internal structure of a flower and briefly explain about types of pollination

$\rm{\fbox{what \: is \: a \: pollination}}$

• Pollination is the process in which the pollen grains from the anthers are transferred to stigma of a flower of the same species.

There are two types of pollination:-

• Self-pollination
• Cross-pollination

$\rm{\fbox{Self-pollination}}$

• It is the one that occurs either within the same flower or between two flowers on the same plant. Here, the pollen grains from the anthers may fall on the stigma of the same flower or the stigma of another flower on the same plant.

$\rm{\fbox{Cross-pollination}}$

This occurs between two flowers on different plants of the same species.

$\rm{\fbox{Agents \: of \: Cross-pollination}}$

• Insects
• Wind
• Water
