Question	Answer
active transport	process requiring energy by which cells move materials against a concentration gradient
contractile vacuole	organelle that some protists such as paramecium possess that collects and expels water
diffusion	net,random movement of particles from an area of high concentration to an area of low concentration
dynamic equilibrium	condition of continuous movemnet of particles across a gradient with no overall change in concentration
endocytosis	active transport of particles into a cell
exocytosis	active transport of particles out of a cell
facilitated diffusion	passive transport of particles such a sugars and amino acids across a membrane by way of transport proteins
fluid mosaic model	property of the plasma membrane wherein many similiar molecules are free to move sideways within their lipid bilayer
hypertonic solution	in cells the condition where the solution outside the cell is more concentrated than inside the cell-causes cells to shrink
hypotonic solution	in cells the condition where the solution outside the cell is less concentrated than inside the cell causing the cell to swell and possibly explode
isotonic solution	in cells the condition where the solution outside the cells is the same concentration as inside the cell
osmosis	the diffusion of water through a membrane depending on the concentration of solutes on either side of the membrane.
passive transport	in cells the movement of particles across a membrane requiring no expenditure of energy.ex-diffusion and osmosis
phospholipid	membrane lipids having phosphate groups attached to them.Plasma membranes of cells are made of these.
plasmolysis	process resulting in a drop in turgor pressure-ie. plants wilting
selective permeability	property of the plasma membrane where it controls what enters and exits the cell.
transport protein	a protein embedded in the cell membrane that can allow molecules to pass back and forth across the membrane
turgor pressure	internal pressure within a cell caused by water in the central vacuole
