Cells have a really interesting way of deciding what can come in and what should stay out. They do this mainly through their cell membranes. Let’s break it down:
Diffusion: This happens when molecules move from a place where there are a lot of them to a place where there are only a few. Imagine spraying perfume in a room! Over time, the smell spreads out so everyone can smell it.
Osmosis: This is a special process for water. It’s when water moves through a barrier that lets some things pass but not others. The water keeps moving until both sides are balanced and even.
The cell membrane acts like a bouncer at a club. It only lets certain things inside and helps keep everything balanced on the inside. This is really important for keeping the cell healthy!
