The Vavilov Center is a special place where scientists keep lots of different kinds of plants. It's like a big garden, but even bigger! In fact, it's so big that it has different sections called "gene banks" where they store groups of plants from all around the world.
The scientists who work at the Vavilov Center really love plants and want to make sure they don't disappear forever. They know that some plants are very important because they're used to make food or medicine. They also know that sometimes plants can get sick and die, so they want to have backup plants that are healthy and can grow well again.
The Vavilov Center is named after a scientist named Nikolai Vavilov who traveled all over the world to study plants. He discovered that some plants can only grow in certain places because they need specific things like sunlight, water, or temperature. That's why the Vavilov Center has all these different plants from different parts of the world!
The scientists at the Vavilov Center take really good care of the plants. They water them, give them fertilizer, and make sure they're not too cold or too hot. Sometimes they even grow new plants from tiny pieces of the old plants – it's like magic!
Overall, the Vavilov Center is a very important place because it helps us understand and protect our planet's plants. And who knows, maybe someday you'll be a scientist who gets to work there and discover something amazing!
