How Do Plants Make Their Food?
The Magical Food Factory Inside Leaves!
Have you ever wondered how plants eat? They don’t have a mouth like us. They don’t order food or cook in a kitchen. So how do they get energy?
Plants are very special. They can make their own food using sunlight! This wonderful process is called Photosynthesis.
Let’s explore how this green magic works!
What Is Photosynthesis?
The word photosynthesis comes from two words:
Photo = Light
Synthesis = To make
So, photosynthesis means “making food using light.”
Plants use:
Sunlight
Water (from soil)
Carbon dioxide (from air)
to make glucose, a type of sugar that gives them energy.
At the same time, plants release oxygen, which all animals and humans need to breathe. Isn’t that amazing?
The Role of Leaves
Leaves are like tiny food factories. Inside the leaves is a green substance called Chlorophyll.
Chlorophyll:
Gives plants their green color
Absorbs sunlight
Helps turn sunlight into energy
That is why most plants are green!
Let’s understand it slowly and clearly.
1️⃣ Roots Absorb Water
The roots of the plant pull water from the soil.
This water travels up through the stem to reach the leaves.
2️⃣ Leaves Take in Carbon Dioxide
Leaves have tiny openings called Stomata.
Through these tiny pores, plants take in carbon dioxide from the air.
3️⃣ Sunlight Is Captured
Chlorophyll in the leaves captures sunlight.
4️⃣ Food Is Prepared
Inside the leaf cells, water and carbon dioxide mix together using sunlight energy.
They change into glucose (plant food).
5️⃣ Oxygen Is Released
During this process, oxygen is formed and released into the air through the stomata.
And that’s how plants feed themselves!
What Happens to the Food?
The glucose made by the plant is used:
To grow new leaves and branches
To make flowers and fruits
To repair damaged parts
To store extra food in roots, stems, or fruits
For example:
Carrots store food in their roots
Potatoes store food in their stems
Mangoes store food in their fruits
Interesting Facts!
Photosynthesis mostly happens during the daytime.
Desert plants also do photosynthesis, but in special ways to save water.
Even tiny algae in oceans perform photosynthesis and produce a lot of Earth’s oxygen!
