Detailed explanation-1: -The leaves prepare food for the plants, using water and carbon dioxide in the presence of sunlight and chlorophyll. This process is called photosynthesis. The prepared food is in the form of glucose.

Detailed explanation-2: -Light work Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means ‘making out of light’.

Detailed explanation-3: -Leaves are the site of the food making process called photosynthesis. In this process, carbon dioxide and water in the presence of chlorophyll (the green pigment) and light energy are changed into glucose (a sugar). This energy rich sugar is the source of food used by most plants.

Detailed explanation-4: -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.
