Question

The process by which plants make their own food is called:

• A. Respiration
• B. Photosynthesis
• C. Transpiration
• D. Fermentation

Hint:

Photosynthesis is the key process by which plants make their food and produce oxygen, essential for life on Earth.

Answer 1

The Correct Option is B

The process by which plants make their own food is called photosynthesis. During this process, plants convert carbon dioxide, water, and sunlight into glucose (food) and oxygen. Step 1: Analyzing each option.

• (A) Respiration: Incorrect. Respiration is the process by which plants and animals break down glucose to release energy, not to make food.
• (B) Photosynthesis: Correct. This is the process by which plants make their own food using sunlight, water, and carbon dioxide.
• (C) Transpiration: Incorrect. Transpiration is the process by which water is absorbed and evaporated from the plant, not involved in making food.
• (D) Fermentation: Incorrect. Fermentation is a process that occurs in some organisms to break down sugar without oxygen, not used by plants for food production.

Step 2: Conclusion.
Thus, the correct answer is (B), photosynthesis. Final Answer:} Photosynthesis.
