How do plants perform photosynthesis to create energy and oxygen?

Plants take sunlight and turn it into food and oxygen, just like a kitchen makes meals from ingredients.

Photosynthesis is how plants make their own energy. Imagine a plant as a little chef in a green kitchen. The sun is like the heat from an oven, it helps cook the meal.

Inside the leaves of a plant are tiny factories called chloroplasts, and they use sunlight to mix water (from the soil) with carbon dioxide (from the air we breathe out). This mixing process turns these ingredients into sugar (which gives the plant energy) and oxygen (which we breathe in).

It's like having a blender that takes water and air, adds some sunshine, and makes a tasty drink, sugar for the plant and oxygen for us.

Sometimes, on a sunny day, you can see tiny bubbles coming out of a pond, those are plants making oxygen underwater! It’s as if the water is bubbling with happy little chefs hard at work.
