Detailed explanation-1: -Leaves prepare food through the process of photosynthesis. So, they are called the food factories of plants. Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize food in the form of glucose using carbon dioxide and water.
Detailed explanation-2: -Leaves are nature’s food factories, converting the light from the sun into energy to help plants grow.
Detailed explanation-3: -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-4: -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.
