Photosynthesis

What Is Photosynthesis?

Photosynthesis is the way green plants make their own food. They use sunlight, water, and a gas called carbon dioxide. The plant’s leaves act like tiny kitchens where the magic happens.

How It Works

1. Sunlight hits the leaf: The green pigment chlorophyll catches the light.
2. Water travels up: Roots pull water from the soil and send it to the leaves.
3. Carbon dioxide enters: Tiny holes called stomata let air in, bringing carbon dioxide.
4. Food is made: The plant changes sunlight, water, and carbon dioxide into sugar, which gives it energy.
5. Oxygen is released: A side‑product is oxygen, which goes back into the air for us to breathe.

Why It Matters

• Food for the planet: All plants, trees, and even some algae use photosynthesis, so they become the base of the food chain.
• Clean air: The oxygen plants release keeps the air fresh for animals and people.
• Energy source: The sugar made in leaves can be stored as starch, giving plants energy for growth and fruit.

Fun Fact

A single big tree can produce enough oxygen for about four people each day!

Remember, every time you see a green leaf, it’s busy turning sunlight into food and fresh air. 🌞🌿
