- A waxy surface protects the leaf from the environment, whilst still letting sunlight through. Leaves make food for the plant, in the form of glucose, a type of sugar. To do this they need Carbon Dioxide from the air, water from the soil and light from the sun. This amazing process is called photosynthesis.

Leaves are delicate organs present on the upper parts of the plants exposed to the sun. They are green in color due to the presence of a pigment named chlorophyll. Unlike other parts of the plant, they are highly active. This shows their active role in plant physiology. Both the formation of leaves and their shedding are also essential for the plan...
Oxygen is vital for life. It reaches our body cells and tissues and generates energyfrom glucose.This energy helps us stay alive and perform all our work.Air has 21% oxygen. When all the animals breathe daily and release CO2, the oxygenratio can go down, leading to suffocation.But green leaves release oxygen during the process of photosynthesis. Thus, they help to maintain the proper oxygen ratio in the air.Besides the consumption of oxygen, we also leave out CO2 during expiration. This release is also further added up when we burn some wood or fossil fuels. This can drastically enhance the carbon dioxide levels in the air, which could be harmful to all the animals on the earth. Interestingly, plant leaves take in CO2 as a part of photosynthesis. Duri...
In general, the presence of green trees is considered necessary for low temperatures during summer. This is true as plants minimize greenhouse gas effects. But the other mechanisms involved are through the leaves of the plants. Leaf pigments absorb lightfrom the sun and store it in the form of chemical energy. Thus, the lightreflected in space from...
Leaves are involved in food production. They prepare sugar, which is stored in fruits, seeds, and tuber (potatoes) of plants. Also, some leaves become succulent and eatable. There are also many green leafy vegetables that are rich in iron and can be used as part of our food. There are thousands of edible leaveswhich can be taken as a part of our di...
Medicine is one of the important uses of the leaf. They are the biggest source of medicine from natural resources. Many leaves like Digitalis, vinca, and aloe are excellent sources of medicine. Digitoxin from the leaves of the digitalis plant is used in case of heartfailure, vincristine from vinca plants is a drug for the treatment of cancer, and a...
Tobacco that is widely used in cigars and other smoking and chewing products is obtained from tobacco leaves.
Few leaves are the source of good quality fiber for manufacturing ropes and threads. Examples of plants whose leaves are used for the purpose include hemp, Henequen, sisal, abaca, etc. These fibers are hard and coarse.
Dyes are the coloring substances used to impart appealing color to food items and medical formulations. They help to mask unpleasant colors and enhance the appeal of the substance. Leaves are also sources of colors and dyes. Unlike synthetic ones, these are obtained from nature, so the process is called eco-dyeing or eco-printing. Many leaves like

Aug 19, 2017 · Function of the Leaf. As one of the most important constituents of plants, leaves have several essential functions: Photosynthesis. The primary function of the leaf is the conversion of carbon dioxide, water, and UV light into sugar (e.g., glucose) via photosynthesis (shown below).
Jul 12, 2023 · Explore the intricate world of plant leaves as we delve into their purpose, structure, types, arrangement, and evolutionary adaptations.
Oct 24, 2024 · The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.
The leaf is one of the most important parts of a plant. Leaves produce food for the plant through a process called photosynthesis. The leaves of different plants vary widely in size, shape, and color.
