Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Plants take in ____ from the air as one key ingredient 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: -Final answer: The part of the plant that takes in carbon dioxide from the air for photosynthesis is the stomata.

Detailed explanation-3: -This process is called photosynthesis and occurs in the chloroplast of the plant cell. Plants take in carbon dioxide through tiny openings or pores in their leaves called stomata. Special cells in the leaves of plants called guard cells open and close the stomata.

Detailed explanation-4: -Plants take in – or ‘fix’ – carbon dioxide from the atmosphere during photosynthesis. Some of the carbon is used for plant growth, and some of it is used in respiration, where the plant breaks down sugars to get energy.

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.
