Answer 2

Answer:

Pollination:

• The process of transfer of pollen grains from anther to stigma belonging to the same flower or different flowers is called pollination.

The two types of pollination are self-pollination and cross-pollination.

Self pollination

• Pollen transfer between the anther and stigma belonging to the same flower is called self-pollination.
• Self-pollination can occur in the bisexual flowers where both androecium and gynoecium are present.

Examples: wheat, rice, apricots, etc.

Cross-pollination:

• Transfer of pollen from the anther to the stigma of different flowers belonging to the same plant or different plants from the same species is called cross-pollination.
• This can occur in both plants having a single reproductive whorl in each flower (unisexual flower) and with both the whorls present in a single flower (bisexual flower).

Examples: grass, maple, etc.

Pollinating agents:

• There is an agent or medium through which pollen grains are transported from the anther to the stigma of the flower during cross-pollination called the pollinating agents.

Some common pollinating agents are wind, water, insects and animals that carry the pollen grains to a different flower.
