seeds

Sexual Reproduction

The pistil and the stamen are parts of the flower that are responsible in the making of seeds in flowering plants

Is the male reproductive organ. It consist of stalk called the filament and an ovoid structure at its tip called the anther. The anther bear the pollen grains.

Stamen

Pistil The pistil is the female reproductive organ found at the center of the flower. It consist of the ovary ,style, and the stigma. An egg cell is formed in the ovule. The ovules, after fertilization, will develops into seed and the ovary surrounding it becomes the fruit of most plants.

Pollination

One of the important function of the flower is to produce seeds.

How?

Pollination

If seeds are to be produced, the pollen grains from the anther must land on the stigma. This transfer of pollen grains to the stigma is called

Pollination

Pollination

Pollination occur mainly by wind and by animals

such as insects and

birds.

Pollination Self

pollination When pollen from a plant’s anther is transferred to that same plant’s stigma, it is called self pollination.

Pollination Cross

pollinationWhen pollen from a plant’s

anther is transferred to another

plant’s stigma it is called cross pollination.
