The raw materials used by green plants for photosynthesis are
A
oxygen and water
B
oxygen and glucose
C
carbon dioxide and water
D
carbon dioxide and glucose
Explanation: 

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: -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-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: -Sunlight, chlorophyll, carbon dioxide, water and minerals are raw materials essential for photosynthesis.

Detailed explanation-5: -Photosynthesis is a process that uses organic chemicals like carbon dioxide and water to synthesize glucose in the presence of light. This reaction occurs inside the living plants in their green leaves. The end products of photosynthesis are glucose, oxygen, and water.
