What is The Calvin cycle (light-independent reactions)?

The Calvin cycle is how plants make food using energy they saved from the sun.

Imagine you have a toy factory that makes candy, but it only works when there’s no light outside, like at night. During the day, the factory gets power from sunlight, and it saves some of that power in little batteries. At night, the factory uses those batteries to keep making candy.

The Calvin cycle is like that toy factory working at night, using stored energy to turn carbon dioxide (a gas plants breathe in) into sugar, which they use for food and growth.

During the day, plants do a special job called photosynthesis, where they catch sunlight and store some of it as energy. This is like charging up their batteries.

At night, when there’s no light, the factory (the Calvin cycle) starts working. It uses that stored energy to change carbon dioxide from the air into glucose, which is a type of sugar. The plant keeps using this glucose for energy and to grow bigger, just like how you need food to play all day!

So whether it’s light or dark, plants are always busy making food, sometimes with help from batteries they made during the day!
