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: -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-4: -Plants during photosynthesis use carbon dioxide. Rate of consumption varies with crop, light intensity, temperature, stage of crop development and nutrient level. An average consumption level is estimated to be between 0.12–0.24 kg/hr/100 m2.

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.
