Detailed explanation-1: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form 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.
Detailed explanation-3: -This process is called photosynthesis and is performed by all plants, algae, and even some microorganisms. To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant’s leaves, flowers, branches, stems, and roots.
Detailed explanation-4: -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. Once they have water and carbon dioxide, they can use energy from sunlight to make their food.
Detailed explanation-5: -Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.
