Vary in shape and size (good diagnosis tool) even within the body
Prokaryotic
Generally Single-Celled Lack of Membrane Bound Nucleous Typically much less complex Smaller Very high surface: volume ration
Eukaryotic
Generally part of a multicellular organism Membrane bound Complex larger high volume:surface area ration
Structural Features of Cells
Description
Driving Function - "Form follows Function"
Size and Number
of cell structures relative to each other
Organization
How cells fit together
Other
Net Charge, Hdrophobidity, Hydrophilicity
Cell Membrane
Contains lipid bilayer and principally composed of modified fatty acids - phospholipids
Organelles
Parts Inside Cells
Nucleous
Holds DNA
Endoplasmic Reticulum
Manufactures protein (Rough ER) Manufactures lipids and carbs (Smooth ER)
Golgi Apparatus
Packages macromolecules to send out/modifies, sorts, adds carbs to give markings onto
Mitochondria
Creates ATP and gives cells energy
Cytoskeleton
Consists of Actin Filaments (in charge of muscle contraction), intermediate filaments, and microtubules "Roads of the Cell" and takes packages from Golgi apparatus and delivers them out of the cell
Cellular Systems Model
The systems approach views the process as a protein producing factory providing biological structure and function required to maintain life.
