PHOTOSYNTHESIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which two substances do plants need for photosynthesis to occur?
A
Carbon dioxide and water
B
Water and Light
C
Light and carbon dioxide
D
Oxygen and glucose (sugar)
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: -Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.

Detailed explanation-3: -Carbon dioxide, water, and light are the ingredients plants need in order to make their food to grow. Carbon dioxide is a gas that we humans breathe out.

Detailed explanation-4: -Water is necessary for photosynthesis, which is how plants use energy from the sun to create their own food. During this process, plants use carbon dioxide from the air and hydrogen from the water absorbed through their roots and release oxygen as a byproduct. This exchange occurs through pore-like stoma on the leaves.
