DENDROLOGY

Detailed explanation-1: -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-2: -Most plants prepare food by the process of photosynthesis. The process by which leaves prepare food using water and minerals from the soil and carbon dioxide from the air in the presence of sunlight and chlorophyll is called photosynthesis.

Detailed explanation-3: -Plants make their own food by a process called Photosynthesis. Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy and stored in the form of starch which can be used later. Photosynthesis is a key process in the growth of plants.
