Question

name any three function each of flower and leaf​

Answer 1

Answer:

1: Photosynthesis :

The process of producing food, known as Photosynthesis, mainly occurs in the leaves of most angiosperms. This process essentially involves the absorption of light mainly by the chlorophyll pigments and the absorption of carbon dioxide via the stomatal pores in the leaves. As a result of the cleavage of the water molecule during photosynthesis, oxygen is generated and released to the atmosphere.

2. Interchange of Gases:

Leaves have numerous tiny openings called stomata. Through these minute pores exchange of oxygen and carbon dioxide occurs during photosynthesis and respiration. During photosynthesis, carbon dioxide enters the leaves and oxygen is given out while during respiration, oxygen enters the leaves and carbon dioxide is given out.

3. Evaporation of Water:

The excess water present in the plant evaporates through stomata on the leaves. This process is called transpiration.

3. Floral induction:

The plant leaves synthesize and translocate the flower-inducing hormone called florigen to the buds.

Storage of Food:

In onion the fleshy leaves or scales of onion store water and food in them. Fleshy and succulent leaves of desert plants always store some water and food in them.

5. Vegetative Propagation:

Leaves of some plants produce buds on them. These buds can grow into new plants. Such leaves are found in Bryophyllum and Begonia.

Some special uses of leaves

In banana, the leaf sheaths provide the physical support, oftenly calledpseudostem, to raise the leaves upward. In a few insect-eating plants such as the pitcher plant, venus fly-trap and sundew, plant leaves are so modified to trap visiting insects, then releasing enzymes and digesting them for their protein which is a source of nutrition. In some plants such as Bryophyllumand Kalanchoe, the leaves are used for asexual reproduction

Answer 2

Answer:

Function of Leaf

It contains chlorophyll which assists the plants in preparation for food. ... A leaf has three basic parts which are petiole, leaf base and lamina. The leaves of the plant help in photosynthesis. Moreover, they help in removing any excess water via stomata.
