Most living things are composed of different kinds of cells specialized to perform different functions.

Explanation:

This is because all of the cells in our bodies start from a single fertilized egg. As cells divide and grow different genes are expressed, resulting in different cell types. Cells differentiate because specific enzymes turn genes on and off in various cell types. Most living things are composed of different kinds of cells specialized to perform different functions.
