HORTICULTURE

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 carbon dioxide required for photosynthesis comes from the air. It enters leaves through the stomata . Water enters the plant through the roots, and is transported to the leaves in the xylem . Oxygen is formed as a product.

Detailed explanation-3: -The process by which leaves prepare their food (carbohydrates) in the presence of sunlight by using water, chlorophyll, and carbon dioxide is called photosynthesis. Oxygen is given out during this process.

Detailed explanation-4: -Carbon dioxide, water, and light are the ingredients plants need in order to make their food to grow. Carbon dioxide is a gas that we humans breathe out.

Detailed explanation-5: -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.
