NEET BIOLOGY

Detailed explanation-1: -Raw materials for photosynthesis are carbon dioxide, water, and sunlight. Carbon dioxide is produced through the exchange of gases. This function is performed by stomata. Water is absorbed by roots from the soil, whether from irrigation or rain.

Detailed explanation-2: -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-3: -Carbon dioxide and water are the main raw materials for the process of photosynthesis. Besides, light energy and chlorophyll are also raw materials for photosynthesis. Sunlight is the energy source, which is essential for photosynthesis to take place.

Detailed explanation-4: -Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product.
