Cell Theory 1. All living things are composed of cells 2. Cells

3. ALL cells come from preexisting cells. are the basic units of structure

and function in all living things. Cell Diversity 1.SHAPE The shape of the cell is based on the function the cell needs to perform. Structure = Function

Different types of cells have different shapes. tructure and Functi Based on the following cell shape, what do you think the function is? Cell Diversity

Cell Shape * Cell Diversity 2. SIZE Cells vary in size from

macroscopic to microscopic Cell Size Demo: See lab handout Size examples Microscopic cells Macroscopic cells What is the largest cell???

The smallest cells = bacteria Ostrich egg Cell Diversity 3. INTERNAL ORGANIZATION: cells contain

organelles to organize their inside material Organelles= tiny organs prokaryote Eukaryote Prokaryotes vs. Eukaryotes Chart
