Photosynthesis for Kids: How Do Plants Make Their Food?
What is Photosynthesis?
Plants don’t eat like people or animals. They make their own food—like tiny green chefs! The process is called photosynthesis.
Let’s break it down:
- Photo means light (from the sun)
- Synthesis means putting together
So, photosynthesis means putting things together using light to make food.
What Do Plants Need to Make Food?
To cook their food, plants need just a few simple ingredients:
| 🌿 Ingredient | Where It Comes From |
|---|---|
| ☀️ Sunlight | From the sun |
| 💧 Water | From the soil, absorbed by roots |
| 🌬️ Carbon Dioxide | From the air |
| 🍃 Chlorophyll | Green part in leaves that catches sunlight |
Chlorophyll is what makes leaves green—and it’s super important for catching sunlight!
How Does Photosynthesis Work? (Step-by-Step)
Here’s how a plant cooks its food in 5 simple steps:
- Roots drink water from the soil and send it up the stem to the leaves.
- Leaves open tiny holes (called stomata) to take in carbon dioxide from the air.
- Sunlight shines on the leaves.
- Chlorophyll traps the sunlight and uses it like energy to mix the water and carbon dioxide.
- This mix creates a sugar called glucose (plant food) and gives out oxygen as a gift to us!
Chemical structure of photosynthesis
What Do Plants Make?
- Glucose—a type of sugar plants use for energy and growing.
- Oxygen—the fresh air we breathe!
So when plants make food, they help us too. That’s teamwork!
Why Is Photosynthesis Important?
Photosynthesis helps:
- 🌱 Plants grow big and strong.
- 🌬️ Make oxygen so we can breathe.
- 🐛 Feed animals that eat plants.
- 👨👩👧👦 Feed people too! (We eat plants and animals that eat plants.)
No photosynthesis = no food and no fresh air!
Fun Photosynthesis Vocabulary (Kid-Friendly)
| Word | What It Means for Kids |
|---|---|
| Stomata | Tiny holes in leaves that breathe in air |
| Chlorophyll | Green stuff in leaves that catches sunlight |
| Glucose | Sugar made by plants for food |
| Xylem | Water pipes inside the plant |
| Phloem | Food pipes that carry sugar to plant parts |

🎯 Leaf Sunlight Test
You’ll need:
- A green leaf
- A small piece of black paper or foil
- Tape
Steps:
- Tape the black paper over part of the leaf.
- Leave it in the sun for 2–3 days.
- Remove the paper and look at the leaf.
🌿 What happened? The part that didn’t get sunlight won’t look as green—it didn’t do photosynthesis!

FACT #1. The energy for photosynthesis comes from light.
FACT #2. During photosynthesis, plants use sunlight, water, carbon dioxide to make their food.
FACT #3. Light energy is converted to chemical energy by chlorophyll.
FACT #4. The green color of leaves is due to chlorophyll.
FACT #5. Leaves change color in autumn because plants slow down the process of photosynthesis
FACT #6. Plants perform photosynthesis in organelles called chloroplasts. There are two parts of chloroplasts, i.e., grana and stroma
FACT #7. Only plants do not use photosynthesis. Rather, some bacteria, such as cyanobacteria, and protists, such as algae, are also producers. These single-celled organisms also contain chlorophyll.
FACT #8. All living things on this planet depend on organic molecules synthesized by plants as a result of photosynthesis.
