Hypertonic
|
high solute, low water. Water leaves cell. cell shrivels
|
|
|
Hypotonic
|
low solute, high water. Water enters. cell swells/burst.
|
|
|
Isotonic
|
Equal solutes in and out. Water moves in and out. cell stays the same. is at equilibrium
|
|
|
|
Passive transport
|
does not require energy

|
|
|
Diffusion
|
Movement of molecules from high to low concentration
|
|
|

Movement from high to low through protein channel
|
|
|
|
Active transport
|
Requires energy moves from low to high

Endocytosis
|
Cell engulfs large particles by folding its membranes
|
For things too big to fit through membrane
|
|
|
Exocytosis
|
cell gets rid of waste

Four phases prophase metaphase anaphase telophase and cytokinesis
|
|
|
|
G2
|
Step before cell division: preparation
|
|
|
