Rabdology is a fancy word that means the study of how things are arranged and organized. It's like when you clean up your toys and put all the cars in one place and the dolls in another. You're organizing your toys and making them easier to find later.
Scientists who study rabdology do this too, but with a lot of different things like cells in the body or the different parts of a plant. They use fancy tools called microscopes to look really closely at these things and figure out how they're arranged.
Knowing how things are arranged is important because it can tell us more about how they work and how they might be connected to other things. So just like you clean up your toys to make them easier to use, scientists study rabdology to learn more about the things they're studying.
