DENDROLOGY

Detailed explanation-1: -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).

Detailed explanation-2: -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’. The foods are called glucose and starch.

Detailed explanation-3: -Leaves perform photosynthesis using the solar energy to produce food in the form of glucose using carbon dioxide and water. Therefore, the simple food that is prepared by the leaves is called glucose.
