Biology Unit 2-Cells
Cell Membrane Transport Drawings
(1) Show that the left box has a HIGHER CONCENTRATION of particles than the right box.
(2) What does “concentration” mean when we are talking about particles?
(3) The picture you drew in #1 shows a gradient of particles. What do you think GRADIENT means?
(4) What is the definition of DIFFUSION?
(5) Draw a picture of DIFFUSION below.
Show that the right box has a HIGHER CONCENTRATION of particles than the left.
Draw an arrow to show the direction the particles will move
Now draw what the two boxes will look like once they reach equilibrium.
(6) What is the definition of OSMOSIS?
(7) Draw a picture of OSMOSIS below.
Show that the left box has a HIGHER CONCENTRATION of water molecules than the left.
Draw an arrow to show the direction the particles will move in.
Now draw what the two boxes will look like once they reach equilibrium.
(8) What is the definition of FACILITATED DIFFUSION?
(9) Draw a picture of FACILITATED DIFFUSION.
The rectangles in between the two boxes represent the “protein channels”.
Show that the right box has a HIGHER CONCENTRATION of particles than the left.
Draw an arrow to show the direction the large molecules will move in.
Now draw what the two boxes will look like once they reach equilibrium.
(10) What is the definition of ACTIVE TRANSPORT?
(11) Draw a picture of ACTIVE TRANSPORT.
Show that the left box has a HIGHER CONCENTRATION of particles than the right.
Draw an arrow to show the direction the particles will move in.
