Welcome!Today we'll dive into photosynthesis, an essential biological process. This lesson will help you understand how plants make their food and why it's vital for life on Earth.
What is Photosynthesis?Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy, stored in glucose. It occurs in the chloroplasts of plant cells and requires sunlight, carbon dioxide, and water.
The Equation for PhotosynthesisThe balanced chemical equation for photosynthesis is: 6CO2 + 6H2O → C6H12O6 + 6O2. This shows how carbon dioxide and water are converted into glucose and oxygen using light energy.

Limiting Factors in PhotosynthesisLimiting factors are conditions that affect the rate of photosynthesis. These include light intensity, carbon dioxide concentration, and temperature. If one is in short supply, photosynthesis slows down.
