The process by which plants make their own food is called photosynthesis.

Photosynthesis is the process where plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar (glucose).

• Sunlight: Provides the energy needed to kickstart the process.
• Water: Absorbed by the roots and transported to the leaves.
• Carbon Dioxide: Taken in from the air through tiny pores called stomata on the leaves.
