Photosynthesis – How Plants Make Food is a vibrant and essential biology course that explores the life-sustaining process at the heart of Earth’s ecosystems. Through photosynthesis, plants, algae, and certain bacteria transform sunlight into chemical energy, producing glucose and releasing oxygen—fueling nearly all life on the planet.

This lesson breaks down the components and stages of photosynthesis, revealing how light, water, and carbon dioxide come together to power the biosphere. Whether you’re a student, educator, or nature enthusiast, this course offers a clear and inspiring look at one of biology’s most vital mechanisms.

🌞 By the end of this course, you’ll be able to:

• Identify the key components of photosynthesis: sunlight, water, carbon dioxide, chlorophyll
• Describe the two main stages: light-dependent reactions and the Calvin cycle
• Understand how plants convert solar energy into glucose
• Explain the role of photosynthesis in producing oxygen and supporting food chains
• Appreciate its impact on Earth’s atmosphere and climate balance
