Chloroplast capture

Okay kiddo, so you know how plants have tiny green things called chloroplasts that help them make food through photosynthesis? Well, sometimes a plant can eat another plant and take its chloroplasts inside its own cells. This is called chloroplast capture!

When a predator plant munches on a prey plant, it can swallow up some of the prey's cells. If those cells have chloroplasts, the predator plant can actually keep those chloroplasts and use them to make food too. This is called "capturing" the chloroplasts because the predator plant "captures" them from the prey plant.

Once the predator plant has the chloroplasts, it can start using them to make food, just like a normal plant. The chloroplasts will stay in the predator plant's cells and continue to photosynthesize, making food for the predator plant.

Chloroplast capture is really cool because it allows predator plants to get more energy from their food. But not all plants can do it - only certain species have the ability to capture chloroplasts. Some scientists think that chloroplast capture might be an important step in the evolution of new plant species!
