* Growth is driven by cell division: You grow because your body produces new cells. This process is called cell division.

* Cells don't always grow bigger: While some cells grow larger in size (like muscle cells), most cells just divide to create more cells.

* Other factors contribute to growth: Growth also depends on:

* Hormones: These chemical messengers regulate growth and development.

* Nutrition: The food you eat provides the building blocks your cells need.

* Genetics: Your genes determine how big you'll likely be.

So, your cells are the building blocks of growth, but other factors are also crucial.
