Draw and label the three types of osmotic pressure
Describe what would happen to the molecules in a drop of ink if dropped into a beaker of water. What is the process called
Contrast endocytosis and exocytosis
In the cell membrane, ion channels serve as
food molecules
information receivers

passagways
The diffusion of water through a membrane is called
exocytosis
osmosis
active transport
endocytosis
Which of the following is NOT a characteristic of active transport
it moves substances against a concentration gradient
it requires energy from the cell
it involves facilitated diffusion
it relies on carrier protien that often function as pumps
Diffusion is the movement of a substance
Through only a lipid bilayer
From an area of low concentration to an area of higher concentration
Only in liquids
from an area of high concentration to an area of lower concentration
An ion channel is a transport protein that
moves substances against a concentration gradient
pumps ions only out of a cell
allow ions to move across the cell membrane so that the ion do not come in contact with nonpolar interior of the lipid bilayer.
has pores that are always open
The sodium-potassium pump
A. helps cells maintain homeostasis
B. carries ions across the membrane from an area of high concentration to an area of lower concentration.
C. Helps maintain a sodium ion gradient, which cells use to conduct electrical impulses
Both A and C
Molecules that are too large to be moved through the cell membrane can be transported into the cell by
osmosis
exocytosis
endocytosis
diffusion
If the concentration of sugar solution is lower outside the cell than inside the cell, which of the following will happen by osmosis
Sugar will move into the cell
Water will move into the cell
sugar will move out of the cell
water will move out of the cell
Which of the following is an example of osmosis
the movement of ions from an area of high concentration to an area of lower concentration
the movement of ions from an area of low concentration to an area of higher concentration
the movement of water molecules from an area of high concentration to an area of lower concentration
the movement of water molecules from an area of low concentration to an area of higher concentration
The excretion of materials to the outside of a cell by discharging them from vesicles is called
exocytosis
osmosis
diffusion
endocytosis
When Particles move out of a cell through facilitated diffusion, the cell
gains energy
uses energy
first gains and then uses energy
does not use energy
