Cellular Transport
Name: ___________________
Passive Transport
Passive transport is the diffusion of molecules from areas of _______ concentration to areas
of _________ concentration. The 5 main types of passive transport include
_______________, ________________, ________________, _________________, and
____________________. All of these processes (do/do not) require enery.
Define simple diffusion: ____________________________________________________________
Define dialysis: __________________________________________________________________
Define osmosis: __________________________________________________________________
Define facilitated diffusion: ________________________________________________________
Define filtration: ________________________________________________________________
Match the description with the osmotic condition:
A. Isotonic
_____ solution with a lower solute concentration
_____ solution in which the solute concentration is the same
B. Hypertonic
_____ solution that would make a red blood cell bursts
_____ solution with a higher solute concentration
C. Hypotonic
_____ solution that would make a red blood cell shrink
Label the tonicity for each solution (isotonic, hypotonic, or hypertonic):
__________
__________
__________
Active Transport
Active transport moves substances from _____ concentration to _______ concentration
______________ concentration gradient. This process (does/does not) require energy. The
energy used is called _______.
Endocytosis
Phagocytosis is referred to as “__________________.”
Pinocytosis is referred to as “____________________.”
