Photosynthesis
Understand the light-dependent and light-independent reactions, limiting factors and chloroplast structure
What you'll learn
- 1
Imagine a 🌱 seed in the soil. It needs food to grow! But plants don't eat like we do — they make their own food using sunlight, water, and air.
- 2
A plant uses its leaves like solar panels ☀️. It takes in CO₂ from the air through tiny holes, and water from the roots 🌊. With sunlight, it turns them into sugar (food) and oxygen!
- 3
What does a plant need for photosynthesis?
- 4
Let's write the word equation for photosynthesis together:
- 5
Drag the inputs and outputs of photosynthesis into the correct boxes.
- 6
What is the main food that a plant makes during photosynthesis?
- 7
Plants store the glucose as starch for later use 🌽. That's why we eat potatoes, rice, and grains — we're eating the plant's stored energy!
