|
|
take oxygen but do not release carbon dioxide
|
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: -The small pores present on leaves help plants take in carbon dioxide and give out oxygen during the process of photosynthesis. These pores are called stomata.
Detailed explanation-3: -Thus, water (H2O) is the source of oxygen released during photosynthesis.
Detailed explanation-4: -Carbon dioxide is released during photosynthesis.
