Transport Notes
1. What are the different transport mechanisms, how do they work?
2. Why is the transpiration-cohesion-tension mechanism more cost effective for trees compared to root pressure?
3. What is the importance of the build-up of minerals/ions in root pressure?
4. What happens to the cohesive forces between water molecules if transpiration is too fast?
5. Why will diffusion work in poriferans, cnidarians and flatworms and not in mammals, avians, etc?
6. What is an interstitial fluid? What is its function/s?
7. Differentiate an open circulatory system to a closed circulatory system.
8. What is the key element for an animal to have a double circulation in the transport of substances throughout its
body? What is the importance of having a double circulation type of transport?
9. Why can amphibians opt to have a single ventricle? What is the effect of having a single ventricle?
10. What are the different blood vessels and their corresponding characteristics and functions?
