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: -Final answer: The part of the plant that takes in carbon dioxide from the air for photosynthesis is the stomata.

Detailed explanation-4: -Examples of raw materials include steel, oil, corn, grain, gasoline, lumber, forest resources, plastic, natural gas, coal, and minerals. Raw materials can be direct raw materials, which are directly used in the manufacturing process, such as wood for a chair.

Detailed explanation-5: -Thus, the correct answer is ‘Carbon dioxide, water, and sunlight’.
