NEET BIOLOGY

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.

Detailed explanation-2: -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.

Detailed explanation-3: -Water is absorbed by the roots of the plant and travels up the vascular system by the tissue known as xylem. Water enters the leaf and absorbs into the photosynthetic cells by osmosis, combining with CO2 to produce glucose and oxygen. Inside the cell, water can be stored in the vacuole.

Detailed explanation-4: -Water is an essential component of the process of photosynthesis. It is a limiting factor as well. One percent of absorbed water is used during the process of photosynthesis.
