What is the process by which plants make their food using sunlight called?

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

Answer: (A)

The process by which plants make their food using sunlight is called photosynthesis. During photosynthesis, plants convert sunlight into chemical energy by taking in carbon dioxide from the air and water from the soil. Using the energy derived from sunlight, they transform these components into glucose, a type of sugar that serves as food for the plant. Additionally, oxygen is released as a byproduct of this process, which is essential for the survival of many living organisms on Earth.

Photosynthesis is vital not only because it provides food for the plants themselves, but it also forms the foundation for most life on Earth, as it contributes to the oxygen in our atmosphere and is the primary source of energy for nearly all ecosystems. Understanding photosynthesis helps us appreciate the integral role that plants play in our environment.
