BIOMOLECULES AND ENZYMES

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: -Green plants make their own food in the presence of sunlight by a process called photosynthesis.

Detailed explanation-3: -They make it themselves! Plants are called autotrophs because they can use energy from light to synthesize, or make, their own food source. Many people believe they are “feeding” a plant when they put it in soil, water it, or place it outside in the Sun, but none of these things are considered food.

Detailed explanation-4: -It acts as their food and provides them energy. Plants need to synthesise their own food because unlike other living organisms, plants can not move and cannot hunt. But, for their sustenance they need food, therefore they have to make their own food.
