Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which substances must a green plant obtain from its environment to carry on photosynthesis?
A
glucose and water
B
oxygen and chlorophyll
C
carbon dioxide and water
D
carbon dioxide and oxygen
Explanation: 

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: -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. Plants also require water to make their food.

Detailed explanation-3: -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-4: -Plants absorb carbon dioxide through small openings called stomata that are on the surface of the leaf. If we zoom in on a plant leaf, so close that we can see the cells, we’ll find tiny openings called stomata. Stomata are holes made from spaces between special cells.

Detailed explanation-5: -The green plants produces food in the form of glucose by utilizing carbon dioxide and water in the presence of solar energy. The green pigment called chlorophyll can trap the solar energy which is used to perform photosynthesis, that finally produces food in plants.
