Movement of Materials Within the Cell:

Notes: Passive Transport

First Review of Passive Transport

Notes: Active Transport

First Review of Active Transport

Online Reviews of Passive & Active Transport:

A. Passive Transport

Diffusion

Osmosis

Osmosis in an Isotonic Environment: (www.cat.cc.md.us) -

Osmosis in a Hypertonic Environment:

Osmosis in a Hypotonic Environment:

Facilitated Diffusion (no ATP used......from high to low concentration)

 

Transport (In french, but does a good job illustrating diffusion, passage through protein channels, cotransport, Na/K pumps, endocytosis & exocytosis.)

 

B. Active Transport

Active Transport: (McGraw-Hill) - 4 Animations & Audio of CoTransport, Na/K Pump, Endocytosis & Exocytosis, and Proton Pump.

Sodium/Potassium Pump: (No text with it but a good animation of this important form of Active Transport)

CoTransport (passage of Na into the cell helps bring Glucose (G) in too!)

Cotransport (McGraw Hill)

Sodium/Potassium Pump combined with Cotransport (The sodium/potassium pump is often coupled with Cotransport to power the active transport of glucose into a cell)

Pinocytosis:

Phagocytosis: Shows both an animation as well as 2 short movie clips of amoebas ingesting other organisms via phagocytosis.

Receptor-mediated Endocytosis: The molecule to be moved into the cell must match up with a receptor on the membrane surface to be moved in.

Exocytosis:

Exocytosis: (BBC Education)


All Cell Topics


To prepare for the final cell test:

A) Review all notes & Handouts.

B) Read Chapters 4, 5 & 6 in the Textbook! (If in a hurry, at least look at the section or chapter review pages.)

C) Answer the practice essay questions:

1. Know how to identify organelles from a diagram of animal or plant cells.

2. Know how to identify structures found in a prokaryotic cell.

3. Know 2 differences between passive and active transport.

4. Be able to give brief explanations of what happens in the following (including whether it is passive or active transport, and whether materials move from low to high or high to low.)

a) diffusion, b) osmosis, c) facilitated diffusion, d) phagocytosis (1 type of endocytosis), e) pinocytosis (1 type of endocytosis), f) exocytosis, g) Na-K Pump, h) Proton Pump, i) Cotransport.

5. Be able to compare & contrast (similarities and differences) between plant and animal cells.

6. Be able to compare & contrast (similarities and differences) between prokaryotic & eukaryotic cells.

7. Be able to list differences between light microscopes and electron microscopes.
