Plant reproduction
Flowers are important for sexual reproduction by plants. They produce male sex cells and female sex cells. These must meet for reproduction to begin in a process called pollination.
Flower structure
The flower is the reproductive organ of many plants.

Pollination
During plant reproduction, pollen grains need to move from the anther of one flower to the stigma of another flower. This is called pollination. Insects can pollinate flowers, and so can the wind. Insect-pollinated flowers are different in structure from wind-pollinated flowers. This table describes some differences:

We depend upon pollination by insects (including the honey bee) for many of our crops. Without them the security of our food would be threatened.
