Cell Theory• All living things are made up of cells. • Cells are the smallest working units of all
living things. • All cells come from preexisting cells
through cell division.

Definition of Cell
A cell is the smallest unit that is capable of performing life
functions.

Two Types of Cells
•Prokaryotic•Eukaryotic

Prokaryotic• Do not have
structures surrounded by membranes
• Few internal structures
• One-celled organisms, Bacteria
