Solution
- When a flower is in a bud stage, we can see a green colour, leaf like structure which cover the whole bud or flower, Each of these green like structure present as an outermost layer is called as sepal. This outer most ring of sepals is known as calyx.
- Petals are the largest part of fl owers. Th ey are oft en attractive, brightly coloured, sometimes sweet scented and attract the insects. Th is ring of petals together is called corolla.
- Inner to this corolla, in Hibiscus, we can observe a long tube on which many stamens are arranged. But in Datura, we can see only fi ve stalked structures, stamens. Th is ring or whorl of a fl ower is called androecium. Each stamens consists of two parts – a stalk called fi lament and a lobe called anther. If you touch these lobes in a mature fl ower, we can get a powdery substance called pollen grains, male reproductive part.
- Inner to this androecium whorl, we can find a female reproductive part of the flower, called Gynoecium. You will find this part with a swollen bottom part. This is the ovary. Seeds are produced in this part. On top of the ovary there is a slender tube like structure called style. The top most sticky tip of the style is stigma.
