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
