Term
nucleus
Definition
{both plant and animal cells}directs all cell activities, stores genetic info (chromosomes)
Term
mitochondria
Definition
{both}releases energy from nutrients for the cell to use
Term
cell membrane [plasma membrane]
Definition
{both}separates the cell from the outside environment controls which molecules enter+leave cell [waste] recognition of chemical signal
Term
ribosomes
Definition
{both}protein synthesis: makes protein
Term
cell wall
Definition
{plant cell} gives the plant its shape

Term
endoplasmic reticulum (E.R.)
Definition
{both} carries protein+other materials from one part of the cell to another (surrounds nucleus)
