The raw materials required for photosynthesis are CARBON DIOXIDE and WATER.

Photosynthesis : Preparation of food by the Green Leaves of a plant from carbon dioxide and water in the presence of Sunlight and chlorophyll is called photosynthesis. Photosynthesis occurs mostly in leaves. Leaves are called the food factories of plants.The process of photosynthesis takes place in chloroplasts containing chlorophyll.

6CO2 + 12H2O ----> (sunlight/chlorophyll) C6H12O6 + 6H2O + 6O2

•Carbon dioxide is obtained from the atmosphere through small openings for stomata in the underside of the leaves.

•Roots of the plants absorb water along with minerals from the soil and transport them to the leaves for photosynthesis.

•Chlorophyll is a green pigment and is usually present in the leaves in structures called chloroplasts.

•Sunlight is the source of energy & chlorophyll traps this energy.

short answer

please

The two needed raw materials for photosynthesis are water and carbon dioxide. The water through the roots of the plants, and carbon dioxide moves into the stomata of the plant by diffusion. On the other hand, during the process of photosynthesis, plants release oxygen into the air.
