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 ….

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

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

***Recommended Quick Revision: Watch this link: AP Lab- The Digestive System http://www.youtube.com/watch?v=RYPg4399K1Q Watch this link: What are Macromolecules http://www.youtube.com/watch?v=GptaygaVo9o&feature=r 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…

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

Blood- Components of blood and their functions. Intro to Blood Cells OPTIONAL Blood- Components of blood and their functions. Intro to Blood Cells http://www.youtube.com/watch?v=_FLjj_Z7SKA The Process of Blood Clotting http://www.youtube.com/watch?v=HFNWGCx_Eu4

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.)
