NEET BIOLOGY

Detailed explanation-1: -Oxygen and water are the raw materials for photosynthesis.

Detailed explanation-2: -Sunlight, water and carbon dioxide are the raw materials; food and oxygen are the products of photosynthesis.

Detailed explanation-3: -The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf. Oxygen, a by-product of photosynthesis, and water vapor exit the leaf. In most land plants, water enters the roots and is transported up to the leaves through specialized cells known as xylem (pronounced zigh-lem).

Detailed explanation-4: -Did you know that oxygen is actually a waste product of photosynthesis? Although the hydrogen atoms from the water molecules are used in the photosynthesis reactions, the oxygen molecules are released as oxygen gas (O2).

Detailed explanation-5: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
