[Blood Groups!] Video Links - Transport in Man

From Part 1 Extra (Blood Groups) of your slides: Transport in Humans, here are some video links to help enhance your understanding of the different blood groups in the human ABO blood group system.


Blood Groups Introduction with Blood Grouping Experiment









What is an Eldoncard? - An example of how a Blood Group Test is done











Blood Groups and Blood Compatibility










Questions to ask yourself:

How many types of Blood Groups are present in the ABO blood grouping system?
Who postulated this theory? 

  • Click on this link to find out more about the person who 1st classified blood into different blood groups: Nobel Laureate: Karl Landsteiner (He won the Nobel Prize in 1930)  

What is an Antigen?
What is an Antibody?
What antigen/s and antibody/ies is/are present in each of the blood groups?

What can you do if you want to find out what blood type are you? And How would you do it?

[Components of Blood]: New website links

My dear Biology Groups,


I've found some links which you can click on if you want to read more about the various components of blood.

[Components of Blood} What we have just learnt! Chapter 8: Transport in Plants

From Part 1 of your slides: Transport in Humans, here is the video link to:


Components of Blood:




Questions to ask yourself:


What are the components of blood?
Can you list some of their functions?
How much blood is there in your body? (depending on whether you are male or female, young or old)
What are some blood vessels that we have learnt in class today?
How would you define an artery and a vein?


Here's another video to help you remember what I talked about in class today:


This video gives you a clear and concise idea of the various components of blood, especially, it gives you an example of a real live centrifuge, and what the test-tube of blood looks like after being centrifuged. However, for us, it provides us with lots of details (when they talk about the functions of the different components of blood) that are not really required in our syllabus but of course, it is always great if you love Biology and want to learn more. :)

A Compilation: Chapter 9, Transport in Plants Video-Clips

My dear Classes :)

Please check AsknLearn for the word doc: VideolinksChapter9! Some of the videos are up here, for your viewing pleasure.

Properties of Water:

What is (i) adhesion, (ii) cohesion? 
How does (i) adhesion and (ii) cohesion help in Capillary Action?








An Introduction: Transpiration:









Transpiration + Factors that Affect Transpiration:








Transpiration with Experiments:








PS: You only need to learn about stomatal transpiration, not lenticular or cuticular transpiration :)




Yours in learning,
