Cell specialization—structure and function

In many multicellular organisms, each type of cell is specialized to perform a specific function.

Analyzing the structure of a cell can help you:


1. Understand what the cell's function is.
2. Understand how the cell's structure helps it complete its job.



Examples
Cheek cells are thin and flat to better fit against the side of the mouth.
