An implanted thing is placed inside something else, often as part of a process. This can happen with objects, animals, or even medical devices.
When we talk about something being implanted, it usually means that someone has put it into another object or body on purpose. For example, an artificial hip might be implanted in a person to help them move around better. Some people get microchips implanted under their skin for security purposes. In a more everyday way, seeds are often implanted in soil so they can grow into plants. If you're watching a movie about animals, you might see scientists implanting animals with tracking devices or other instruments.
