Detailed explanation-1: -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.

Detailed explanation-2: -When it comes to photosynthesis, the most important parts of the plant are the leaves. Their cells and structures are specialized to take in light and allow for gas exchange with the air around them. They also contain vascular structures that transport water from the roots into the cells that carry out photosynthesis.

Detailed explanation-3: -The most common and critical type of photosynthesis takes place in chlorophyll‐containing plants, algae, and cyanobacteria. These organisms capture radiant energy of the sun and, by utilizing carbon dioxide and water, convert it to chemical energy stored in molecules of carbohydrates.

Detailed explanation-4: -Leaves are considered to be the main organs of photosynthesis and transpiration in most plants. Food is prepared by leaves by performing photosynthesis. Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and food in the form of glucose.

Detailed explanation-5: -Leaf contains minute pores called stomata where gaseous exchange and transpiration occurs. The main functions of leaves are photosynthesis, exchange of gasses and transpiration.
