The Cell Ch 3

TERMDEFINITION
Cell Theory All organisms are composed of one or more cells, all organism structure and fx are due to the activites of its cells, cells come from pre-existing cells
Light microscope Visible light is focused on specimen
Electrom microscope Uses beams of electrons which have shorter wavelengths
Squamous thin and flat
Cuboidal Cube-shaped
Columnar Rectangular
Spheroid Round
Discoid Disc shaped
Fusiform Joint
Fibers long and slender
Stellate Star like
Apical surface Top
Lateral Sides
Basal Bottom
Filtration Particles pushed through membrane by hydrostatic pressure
Bulk Flow Collective movement of substances in one direction due to force
Diffusion net movement from high to low concentration of molecules
Diffusion Rates Affected by: Temperature,Molecular Weight,Concentration, Surface Area,and Permeability
Osmosis diffusion of Water from an area of high concentration of molecules to low
Osmotic Pressure hydrostatic pressure on one side of mebrane strong enough to resist osmosis
Hypertonic more solute, less water; causes crenation
Hypotonic less solute, more water; may lyse(burst)
Tonicity ability of solution to effect the volume and pressure within a cell
Dialysis diffusion of solutes through a selectively permeable membrane
Facilitated diffusion movement of solute down a gradient with help of carrier protein
Carrier mediated Diffusion uses carrier protein embedded in CM
Active transport carrier mediated up a cancentration gradient
Co transport Carries 2 molecules
Symport binds 2 molecules, moves in same direction
Antiport 2 solutes moved in oppsite direction
Bulk transport Large polymers, droplets, and particles are moved across membrane
Exocytosis To outside of cell
Endocytosis to inside of cell
Phagocytosis engulfs, eats large particles
Pinocystosis cell drinking
