Detailed explanation-1: -Carbon Dioxide (CO2)-Plants obtain CO2 from the atmosphere via stomata. Water-Plants take water from the earth and transmit it to their leaves via their roots. Sunlight is the only source of light that the chlorophyll and other green elements of the plant absorb.

Detailed explanation-2: -One of the major differences between plants and animals is plants’ ability to manufacture their own food. This process is called photosynthesis, which literally means “to put together with light.” To produce food, a plant requires energy from the sun, carbon dioxide from the air and water from the soil.

Detailed explanation-3: -Plants need energy from the sun, water from the soil, and carbon from the air to grow. Air is mostly made of nitrogen, oxygen, and carbon dioxide. So how do plants get the carbon they need to grow? They absorb carbon dioxide from the air.

Detailed explanation-4: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Detailed explanation-5: -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. Glucose is used by plants for energy and to make other substances like cellulose and starch.
