he Nucleus--nuclear envelopecontainsnuclear poresfor some things to enter and exit (nucleoplasmwithin)--chromatinis DNA and proteins, when the cell begins to divide, chromatin condenses and formschromosomes--DNA remains in the nucleus, it sends instructions to the cytoplasm viamessenger RNA--RNA directs the synthesis of proteins onribosomesin the cytoplasm--Nucleolusassembles ribosomes within the nucleus, ribosomes contain the "tools" to construct proteinsMitochondria - The Cell's Chemical Furnaces--contains its own DNA, support for Endosymbiosis Theory--singular is "mitochondrion"--2 membranes, one smooth outer membrane, and an inner membrane folded into layers calledcristae--Cristae has two compartments: thematrixand the intermembrane space--mitochondria divide before cell division, they are not synthesized like other cell parts--function to store energy for cell use. Energy is stored in the form ofATP- adenosine triphosphate
