Where Is Pollen Located in a Flower?

Save

Flowering plants depend on pollen for fertilization and reproduction. Pollen is made up of small grain-like particles that are carried from flower to flower by the wind, insects and small animals.

Reproduction

  • Flowering plants, like animals, reproduce sexually. Flowers have both male and female parts and require the joining of a sperm and an egg to produce seeds.

Male Parts

  • The male part of the flower is called the stamen. The stamen has a thin filament tube base and a thick pod-like top called the anther.

Pollen Production

  • Pollen is produced in sacs inside the anther. When the pollen grains mature, the anther releases them.

Female Parts

  • The female part of the flower is the pistil, which is a long tubular receptacle. The sticky top part of the pistil is called the stigma.

The Ovule

  • The base of the pistil contains the ovary, inside of which is the ovule, the embryo sac and the embryo sac's egg.

Fertilization

  • Each pollen grain contains sperm cells. When a grain sticks to the stigma of a plant, the sperm cells travel down the pistil and fertilize the egg.
