Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Plants need ____ for photosynthesis
A
oxygen
B
soil
C
carbon dioxide
D
sugar
Explanation: 

Detailed explanation-1: -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-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: -Photosynthesis is a series of chemical reactions divided into two stages, the light reactions and the Calvin cycle. During the first stage, water is used and oxygen is produced. In the second and final stage, carbon dioxide is used, and glucose isproduced.

Detailed explanation-4: -Overall equation for photosynthesis 6 molecules of carbon dioxide are required, one for each carbon atom in glucose. 6 molecules of oxygen are produced as a by product of water oxidation. Sunlight provides the free energy needed to make the endergonic pathway proceed.

Detailed explanation-5: -Leaves need oxygen and carbon-dioxide (for photosynthesis).
