Answer 1

Flower:

1. A flower is a reproductive part of a plant.
2. A flower consists of four parts: sepals, petals, stamens, and a pistil.

The vegetative parts include:

1. Sepals: The leaf-like part of calyx that encloses the petals is called sepal.
2. Petals: The brightly colored part of the corolla of the flower, often fused together to form a flower are called petals.

The reproductive parts include:

1. Stamen: The male fertilizing part of the flower is called the stamen.
2. Pistil: The female fertilizing part of a flower is called a pistil.

Stamen that is androecium includes:

1. Filament: The stalk-like structure of stamen, that holds the anther above is called a filament.
2. Anther: The bulbous part of the stamen, that holds pollen grains within is called the anther.
3. Pollen grains: Highly reduced microgametophytes that produce male gametes are called pollen grains.

Pistil that is gynoecium includes:

1. Ovary: The part of gynoecium that holds the ovules, situated at the point of connection of sepals and petals, is called the ovary.
2. Ovules: Megasporangium, where production of female megaspores takes place, is called an ovule.
3. Stigma: The sticky part of the gynoecium, where the pollen grains adhere during fertilization is called stigma.
4. Style: The stalk-like structure of gynoecium that connects the stigma to the ovary, and functions as a passage for the pollen grain to pass is called style.
