Cellular model

Cellular model is like a 3-dimensional model made up of lots of tiny cells. Each cell is like a tiny container that can hold different kinds of things like water, air, or even people. The cells are connected to each other in a way that forms a big structure like a wall, a building, or even a city. So, if you want to think about how a building is put together, you can imagine it like a cellular model where all the cells fit together to make something bigger.
