1 LS Biology Revision 2012 Are you familiar with these?
Watch the videos that I have selected for each topic and make sure you take down some of the notes. Make sure you watch the Recommended Quick Revision links for each topic ….

2 Cells What differentiate a prokaryote from a eukaryote
Identify the parts of a cell and state their functions. Make comparison of the structural differences of the cell types- plant and animal cells Refer to PPT- Cells Structures and Functions Refer to WS Cells –Topical Quiz Refer to Summary Cells Structures and Functions

3 ***Recommended Quick Revision:
Watch this link for Quick Revsion: AP Lab-A Tour of the Cell Just make sure you have time to get through these 3 links for your revision… You may visit the rest of the links (on the next slide) when you have more time. :D

4 Watch this link : Comparing Animal and Plant Cells
OPTIONAL: Watch this link : Comparing Animal and Plant Cells Watch this link : The Cell Theory (higher order –FYI only) yUEbPI Watch this link: Structures in Eukaryotic Cells Watch this link: Cell Biology

5 Movement of Substances
Define the terms “diffusion” and “osmosis” and give e.g. in the biological system Refer to PPT on Osmosis and Diffusion Refer to WS Movement of Moleules Quiz 1, 2 (Quiz 2 is still with me :C but Mark Scheme has been posted last week) ***Recommended Quick Revision: Watch this link: AP Lab- Diffusion &Osmosis Watch this link to Recap on Surface Area to Volume Ratio and its importance in a cell system

6 Watch these links: Surface Area to Volume Ratio in Cells
OPTIONAL: Watch these links: Surface Area to Volume Ratio in Cells 0ZHLJGVTY fP9yb4Qxlo Watch this link: AP Lab-Plasma Membrane (FYI) v=dqdlrUoIdrg&feature=related

7 The Mammalian Digestive System
Describe the “Mechanical’ and ‘Chemical” processes. State where these processes take place? Explain how they aid in the break down of food. Digestive enzymes- give examples and its specific actions… (e.g. carbohydrase break down carbohydrate into simple sugar..) Organs- identify the parts and their functions Refer to Overview Digestive System Refer to Summary Digestive System Refer to WS Digestive System Quiz 1, 2 &3

8 ***Recommended Quick Revision:
Watch this link: AP Lab- The Digestive System Watch this link: What are Macromolecules elated If you wonder if you have clearly understood this topic… Imagine you have a fish burger for lunch… trace the fate of this fish burger in your digestive system…

9 Human Transport System
The Heart –Label the parts and state their functions Refer to WS Anatomy of the Heart. Blood vessels- Identify the types of blood vessels and state their functions. Make comparison based on their structural differences. Refer to Flow of Blood thru Blood Vessels

10 Blood- Components of blood and their functions. Intro to Blood Cells
OPTIONAL Blood- Components of blood and their functions. Intro to Blood Cells The Process of Blood Clotting

11 Heart associated diseases-CHD
Application-What causes CHD? What are some preventive measures? How poor diet and smoking cause a higher risk of having CHD Why it is important to exercise? What are some current trend in treating patient with CHD? CABG Stent- Must read the *essential reading on CHD Refer to Summary Circulatory System Refer to WS Circulatory Quiz 1,2,3 & 4. (Apologies, I am still marking your Quiz 4… but the proposed mark scheme has been posted last week.. You may want to refer to them for your revision.)

12 Watch this link: Heart Anatomy
***Recommended Quick Revision The Cardiac Cycle v=jLTdgrhpDCg&feature=related Watch this link: Heart Anatomy Watch this link: *Cardiac Cycle Watch this link: Understanding Heart Disease t=PL9CCF6359FF85D1B9 Watch this link: Stent

13 Watch this link: AP Lab- The Circulatory System
OPTIONAL Watch this link: AP Lab- The Circulatory System Watch this link: The Circulatory System (Simplified) Watch this link: What is a heart attack? Watch this link: Cholesterol and CHD Watch this link: CABG

14 Ecology NOT TESTED!

15 Pathogen and Diseases NOT TESTED!

16 LADIES ARE YOU PREPARED???
