Structure of a Flower
The flower structure comprises four major parts or whorls—known as the calyx, corolla, androecium, and gynoecium.
Diversity of Flowers:
Flowers come in a range of sizes and shapes, but their anatomy, in general, is the same: sepals, petals, stamen, and carpel. A whorl, or circular positioning, is created by arranging these parts in a circular pattern.
Flowers come in various forms:
- Complete flower - The sepals, petals, stamens, and pistil all constitute a complete flower.
- Incomplete flower - An incomplete flower is one that lacks one or more of these structures.
Parts of a flower:
- Vegetative Part: A flower's vegetative component comprises the following:
- Petals
- Sepals
- Reproductive Part: Flowers consist of the reproductive organs of the plant. A flower's reproductive parts involves the following:
- Pistil
- Stamen
- Leaf
- Stem
- Receptacle
