|
plasma membrane |
phospholipid bilayer with proteins, cholesterol and glycolipids Function: selectively permeable |
|
|
passive transport |
diffusion (simple, facilitated, osmosis) movement of particles from high to low, smaller |
|
|
facilitated diffusion |
aided by protein channel or carrier, proteins show specificity to polar molecules |
|
|
osmosis |
diffusion of water |
|
|
osmolarity |
total concentration of solute particles in a solution, lots of solute, lots of osmolartiy |
|
|
active transport |
uses ATP to move solutes across a membrane. Movement from low to high concentrations |
|
|
Vesicular Transport |
Uses vesicles to move solute. Endo/exocytosis |
|
|
Membrane potential |
difference in voltage across a membrane. Inside is more positive than outside because of diffusion of ions |
|
|
Mitosis |
cell reproduction, occurs in body cells, one division, results in 2 cells (genetically identical) |
|
|
meiosis |
formation of gametes, occurs in sex cells, 2 divisions, results in 4 cells (gentically different) |
