FLOWERS, FRUITS, AND SEEDS
• A flower is the reproductive organ of a plant.
• Petals are colourful structures that surround the inner parts of the flower.
• Carpel (pistil) is the female reproductive part of the flower.
• It has three parts:
A sticky top portion called stigma.
An enlarged base called ovary.
A stalk called style that connects stigma and ovary.
• The ovary contains tiny ball-like structures called ovules, which later become seeds.
• Sepals are the green, leaf-like structures at the base of the flower.
• Sepals protect the flower during its development and support the petals when the flower blooms.
Stamens are the male reproductive parts of a flower.
• Each stamen has two parts:
A thin stalk called filament.
A knob-like structure called anther.
• The anther produces a powdery substance called pollen.
• For a flower to develop into a fruit and form seeds, pollen grains must be transferred from its anthers to the stigma.
