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.
