a thin, flexible barrier that all cells are surrounded by

a strong supporting layer around the membrane

a double layered sheet that the composition of nearly all cell membranes are formed by ____

the mass of solute in a given volume of solution, or mass/volume

process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated

when the concentration of the solute is the same throughout the a system

the diffusion of water through a selectively permable membrane

when the concentration of two solutions is the same

when comparing two solutions, the solution with the lesser concentration of solutes

when comparing two solutions, the solution with the greater concentration of solutes

facilitated diffusion

molecules, such as glucose, that cannot diffuse across the cell membrane's lipid bilayer on their own move through protein channels instead

requires energy,generally carried out by transport proteins or "pumps" that are found in the membrane itself

the process of taking material into the cell by means of indofoldings, or pockets, of the cell membrane

extensions of cytoplams surround a particle and package it within a food vacuole

process by which a cell takes in liquid from the surrounding environment

process by which a cell releases large amounts of material

cells throughout an organelle can develop in different ways to perform different tasks

a group of similar cells that perform a particular function

group of tissues that work together to perform closely related functions

group of organs that work together to perform a specific function
