Detailed explanation-1: -Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.

Detailed explanation-2: -Plants need three main ingredients to make their food: water, carbon dioxide and sunlight. Plants take up the water that they need from the soil through their roots. Carbon dioxide is a gas found in the air; plants can take in this gas through tiny holes in their leaves.

Detailed explanation-3: -Photosynthesis is the process by which plants use energy from the sun to make food. They use carbon dioxide from the air and water from the soil to make sugar and oxygen. Most plants release oxygen only during the day, when the sun can power photosynthesis.

Detailed explanation-4: -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-5: -The component of air used by green plants to make their food is carbon dioxide. Plants utilise carbon dioxide, sunlight and water to make their food and release oxygen into the atmosphere in the process. This process is called Photosynthesis. Q.
