LOCATION

DESCRIPTION

FUNCTION

Cell Wall

Plant, Fungi, & Bacteria, but not animal cells

>> Outer layer >>Rigid & strong
>>Made of cellulose

>>Support (grow tall)
 >>Protection >>Allows H2O, O2, CO2 to diffuse in & out of cell

Cell Membrane

All cells

>>Plant - inside cell wall >>Animal - outer layer; cholesterol >>Double layer of phospholipids with proteins >>Selectively permeable

>>Support >>Protection >>Controls movement of materials in/out of cell
>>Barrier between cell and its environment >>Maintains homeostasis

Nucleus

All cells except prokaryotes

>>Large, oval >>May contain 1 or more nucleoli >>Holds DNA

>>Controls cell activities >>Contains the hereditary material of the cell

Nuclear membrane

All cells except prokaryotes

>>Surrounds nucleus >>Double membrane >>Selectively permeable

>>Controls movement of materials in/out of nucleus
