Cell polarity

Alright kiddo, so you know how everything in our body is made up of tiny building blocks called cells? Well, these cells are pretty amazing because they have something called polarity.

Think of it like your own body. You have a top and a bottom, a left side and a right side, and everything is organized in a certain way. That's kind of how cells work too!

The top of a cell is called the apical side and the bottom is called the basal side. The sides of the cell are also different from each other. These differences in the structure and function of the cell's different sides are what we call cell polarity.

Cell polarity is really important because it helps cells do their jobs properly. For example, if a cell in your stomach didn't have polarity, it might not be able to properly digest your food. It's kind of like how your hands have different jobs - your left hand might be better at writing while your right hand is better at throwing a ball.

Scientists study cell polarity to understand how these building blocks work and help keep us healthy. And, just like you learn about your body in school, scientists are always learning new things about how cells work together in our bodies.
