What are the main cell parts?
Three Main Cell Parts• BOTH plant and animal cells have three main cell

• Each main part has a special and important job to do!
• The three main parts are:
1. Cell membrane (also called plasma membrane)
2. Cytoplasm3. Nucleus
Cell Membrane
Thin structure that surrounds the cell
FUNCTION:Controls what goes in and out of the cell
Cell Membrane
Rat neurons
Cell membranes come in many different shapes:
Human redblood cells
Human heartmuscle
Cytoplasm

FUNCTION:Thick soup that cell parts swim in; also helps hold up cell shape
Cytoplasm
Yeast cell Euglena
Nucleus
Control center of the cell
FUNCTION:Holds instructions for: 1. all cell jobs2. making a new cell
Nucleus
Human epithelial cells Human fibroblast
