Question

The process by which plants produce their own food using sunlight is called:

• A. Photosynthesis
• B. Osmosis
• C. Metamorphosis
• D. Fermentation

Answer 1

Answer:

A. Photosynthesis

• Photosynthesis is the process by which plants use sunlight, carbon dioxide, and water to produce their own food (glucose) and release oxygen.

• B) Osmosis – The movement of water across a semi-permeable membrane, not related to food production.

• C) Metamorphosis – The biological process of transformation in animals (e.g., caterpillar to butterfly), not plants.

• D) Fermentation – A process used by microorganisms to produce energy without oxygen, not how plants make food.
