Detailed explanation-1: -Chlorophyll’s job in a plant is to absorb light-usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.

Detailed explanation-2: -Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

Detailed explanation-3: -Chlorophyll is a green colour pigment present in the leaves of the plants. It helps the plants to make their food by absorbing sunlight.

Detailed explanation-4: -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-5: -Leaf prepares food for plants by the process of photosynthesis. Leaf has abundant stomata for gaseous exchange and performs the function of respiration. The leaf is the main site of water loss through the process of transpiration.
