Osmosis - AP Biology (Quiz #1) Flashcards

7368052939	diffusion	entering and leaving cells by a passive process (no energy) random movement of molecules but is directed from areas of high concentration towards regions of lower concentration in order to reach an equilibrium.	0
7368063874	simple passive diffusion	when small molecules pass through the lipid bilayer of a cell membrane	1
7368068772	selectively permeable	the fact that the membrane has tiny pores or holes allowing certain substances to move across it	2
7368077952	osmosis	the diffusion of water molecules across a membrane (typically a cell membrane)	3
7368091697	tonicity	the relationship between the concentrations of solutes on either side of the membrane which determines the direction and extent of diffusion based on concentration being either greater than, less than, equal to	4
7368101402	hypotonic	lower concentration of solutes	5
7368103796	isotonic	equal concentration of solutes normal	6
7368114591	hypertonic	greater concentration of solutes	7
7368135796	cytolysis	rupturing of the cell because it's so swollen	8
7368140256	turgor pressure	plant cells have a rigid cell wall so that if excess water is bathed among cells, the wall pushes back so that the cell doesn't inflate with water and burst	9
7368155338	plasmolyzed	deflated, and/or dried out	10
