Learn: Photosynthesis

Welcome!Today we'll learn about photosynthesis, an essential process for plants and life on Earth. Let's explore how it works step by step.

What is Photosynthesis?Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen. This process provides energy for plants to grow and produces oxygen for us to breathe.

The Role of ChlorophyllChlorophyll is the green pigment found in chloroplasts of plant cells. It absorbs light energy from the sun, which is needed for photosynthesis to occur.

Reactants of PhotosynthesisPhotosynthesis requires carbon dioxide (from the air) and water (from the soil). These are the reactants needed to make glucose and oxygen.

Products of PhotosynthesisPhotosynthesis produces glucose, which provides energy for the plant, and oxygen, which is released into the atmosphere for other organisms to breathe.

The Photosynthesis EquationThe photosynthesis equation is:Carbon dioxide + Water → Glucose + Oxygen

How does light intensity affect photosynthesis?Light intensity affects the rate of photosynthesis. In brighter light, plants can perform photosynthesis faster, up to a certain point. However, very low light reduces the rate significantly.

Review Time!Great work! You've learned about photosynthesis, including how it works and why it's important. Now let’s test your understanding with a few questions.
