Answer 2

Answer:

Any angiosperm's reproductive unit can be described as a flower. Angiosperm flowers engage in sexual reproduction. A typical flower has an attractively modified stem with a condensed axis. A flower has four distinct parts: the calyx, corolla, androecium, and gynoecium. The androecium and gynoecium sections of a flower contain, respectively, the male and female reproductive organs.

These are the components of a flower:

The Androecium (male reproductive organ) is composed of stamen whorls. Stamen consist of the filament (long and slender stalk) and anther (structure with two lobes). A typical anther that contains pollen grains is bilobed.

The innermost section or whorl of a flower is known as the gynoecium. It consists of pistils, the female reproductive organs of flowers. A pistil consists of three parts: the stigma, the style, and the ovary.

It links the ovary to the stigma.

b. Stigma - It acts as a container for the pollen grains.

c.Ovary - The extended base on which the style rests. Each ovary contains one or more ovules attached to a placenta that resembles a cushion. After fertilisation, ovules become seeds and ovaries become fruit.

Calyx (accessory organ bearing sepals) - The calyx is the outermost whorl of a flower. They are composed primarily of sepals. They are green, leaf-like structures that cover and protect the flowers and attract pollinating insects during the bud development stage. When the sepals in a flower arrangement are separated, they are polysepalous, whereas when they are fused, they are gamopetalous.

4. Corolla - The corolla of a flower is a layer that is found within the calyx. It consists of beautifully coloured petals and a flower's vibrantly coloured whorl. Such petals aid in luring and attracting pollinating insects. Flowers with separate petals are referred to as polypetalous, while those with fused petals are referred to as gamopetalous. Individual corolla units are composed of petals. The inner vital organs (i.e., the stamens and carpels) are surrounded by colourful petals that attract pollinators.
