net movement of particles from an area where there are many
particles of the substance to an area where there are fewer
condition in which there is continuous movement but no overall
change in concentration
form of transport that uses transport proteins to move other ions
and small molecules across the plasma membrane
diffusion of water across a selectively permeable membrane
solution in which the inside of the cell and the solution it is in have
the same concentration of water and solutes
solution that has a lower concentration of solutes than in the cell
solution that has a higher concentration of solutes than in the cell
using energy to move substances from a region of lower
concentration to a region of higher concentration
process by which the plasma membrane surrounds a substance
outside the cell and moves it inside the cell

inside the cell and moves it outside the cell

Make a concept web to show the main ideas and
important details in this chapter, and the relationships between the facts you learned.
Hint: You might find it easier to list the facts or topics you want to include first, then decide
how to connect them in the web.
