How do plants reproduce? Flowers are the organs that make seeds in flowering plants. The seeds grow into new plants. Several processes and all parts of a flower are needed to make seeds.

What are the parts of plants? Parts of flowers: Sepals – the small, green leaves below the petals Petals – the colorful part of the plant Stamens – smaller stalks surrounding the pistil, the male part of the flower Pistil – small, knoblike structures, the female part of the flower

What are the parts of plants? Pollen on the move: In order for a seed to form, pollen has to get from a stamen to a pistil. Animals play a big part in making this happen. Pollen needs to land on a pistil, then a thin tube forms and reaches the ovary. Once the tube reaches the ovary, the sperm cell from the pollen combines with the egg cell in the ovary in a process called fertilization.
5
What are the parts of plants? After fertilization takes place a lot of changes happen to the plant. The petals and stamens dry up and fall off, because they are no longer needed. The fertilized egg inside the ovary develop into a seed. The ovary at the base of the pistil grows large and develops into a fruit.
