functions of a leaves..
and functions of a flower ​

Answer 1

Answer:

Functions of a flower.

i) Leaves undergo the process of photosynthesis to make food for the whole plant.

ii) Leaves undergo the process of transpiration to reduce the excessive water present in them.

Functions of flower.

Flowers main function is to undergo reproduction of plants. Since the flowers are the reproductive organs of plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma.

Answer 2

Answer:

Functions of Leaf:

•Photosynthesis: This is the most important function of a leaf. They contain chloroplasts which have the pigment chlorophyll that is responsible for helping in photosynthesis. The prepared food is transported to the other parts of the plant via phloem tissue.Helps the plant

•breathe: The epidermis of the leaf contains guard cells that control and regulate the small pores on the undersurface of the leaves. These pores are called stomata. Stomata are responsible for regulating water in and out of the cell. It is also responsible for the exchange of gases across the epidermis.

•Storage of food: In some plants, the leaves are modified to store food. These plants generally have succulent leaves as seen in xerophytic plants.

Functions of Flowers :

The Female Reproductive Organ: The Carpel

The female parts of a flower consist of an ovary, which contains one or more ovules, a style and the stigma. The ovary is at the base of the flower.

From the ovary, extends a tubular structure called the style and on the top of the style is a surface receptive to pollen called the stigma.

The stigma can take many different forms, most of them designed to help trap pollen. There are many variations on this basic structural theme.

After fertilization the ovule becomes the seed and the ovary becomes the fruit.

The Male Reproductive Organ: The Stamen

The male parts of a flower consist of one or more stamens. Each stamen is made up of paired anthers (sacs containing pollen) on a filament or stalk.

The anthers are the orange/yellow structures often seen in the centre of a flower.

Pollen from the anthers of one flower is transferred to the stigma of another usually either by wind, or by animals, especially insects.
