Photosynthesis is the process by which green plants, algae, and some bacteria use sunlight to make their own food. They take in water from the soil, carbon dioxide from the air, and use the energy from sunlight to produce glucose (a sugar) and oxygen. This process is essential for life on Earth as it provides food and oxygen for living organisms.
Simple Definition
Photosynthesis is how plants make food using sunlight, water, and carbon dioxide, producing oxygen and sugar (glucose) in the process.
Key Points
- Plants use chlorophyll (green pigment) to capture sunlight.
- Carbon dioxide enters the plant through leaves, and water is absorbed by roots.
- Energy from sunlight converts these into glucose for food and oxygen is released as a byproduct.
This process supports almost all life by producing oxygen and food from sunlight energy.
