Cell Membrane/Plasma Membrane

Holds everything together; regulates what enters and exits cell; communicates with other cells via protein receptors; in both cells

Cell Wall

Helps protect cell from damage; maintains cell's shape; provides structure; only in plant cells


Creates/uses microtubules to help with cell division; movement of chromosomes during animal cell division; only in animal cells


Takes unusable sunlight to usable chemicals; produces glucose; converts energy; powers photosynthesis; only in plant cells


Helps move mucus in humans; transportation; only in animal cells


Supports by filling inside with aqueous solution; holds organelles and cytoskeleton; 1st step of cellular respiration takes place in cytoplasm; in both cells


Supports cell expansion and growth; only in animal cells


Transportation; only in animal cells


Transports vesicles; stores proteins before they're shipped out; assists in lysosome production; modifies, stores and ships things to the endoplasmic reticulum; in both cells

Micro/Intermediate Filaments

Helps cell move and changes shape; makes up cytoskeleton with microtubules; in both cells


Recycles damaged cell parts; stores and destroys bacteria if it enters cell; stores digestive enzymes; digests cell's food and stores waste; apoptosis: programmed cell death; only in animal cells


Anchor and move organelles; makes up cytoskeleton with filaments; in both cells


Releases products of glucose (CO2+H2O+ATP); carries out cellular respiration; creates ATP (energy currency of cell); see breakdown process diagram on written table; in both cells

Nuclear Envelope/Nuclear Membrane

Allows RNA to leave; holds nucleus; controls flow of materials into and out of the nucleus; double membrane; protects DNA by separating/protecting it from rest of cell; in both cells

Nuclear Pore

Allows RNA to leave; "pores" that allow things in and out of the nucleus; regulates what enters and exits by its very small size; in both cells


Contains DNA; controls all cellular activities; in both cells


Makes building blocks of ribosomes (RNA); in both cells


Breaks down toxins, specifically peroxide (H2O2); digests fatty acids; holds digestive enzymes; in both cells

Ribosomes (Bound)

Makes proteins used outside cells; where protein synthesis takes place; attached to something else; in both cells

Ribosomes (Free)

Makes proteins used inside cells; where protein synthesis takes place; not attached to something else; in both cells

Rough ER

Transports vesicles to Golgi; ribosomes (bound) in Rough ER; makes membranes and modifies proteins; in both cells

Smooth ER

No ribosomes; detoxifies drugs (Smooth ER found in liver); synthesizes (makes) lipids and stores calcium; in both cells

Vacuoles (central and regular)

Water pressure allows plants to move; functions as ribosomes and regulates growth; stores water; can store toxins; stores food; central vacuole in plant cells, regular vacuoles in animal cells
