October 28, 2011 Asymmetric division |
||||||
To those of you who attended the class on October 28, On October 28th we discussed what "asymmetric division" is . We looked at several scenarios of cell division, and tried to figure out whether each division can be classified as an "asymmetriv division". I did not provide an Yes/No type answer to each examples, because there is no absolutely correct definition of "asymmetric division", and for each definition there may be a "grey zone". In developmental biology, goal is not the "classification" per se, but a deeper understading of the phenomenon. I hope attending this class provided an opportunity to for you to re-think critically about things that you thought you knew. For your "entertainment", below I reproduce a few examples of cell divisions that I showed during the class. Take a look at them again and try to build your opinion on whether or not they should be classified as "asymmetric division". This is neither a homework nor an assignment that will be used to determine your grades. It is provided simply to aid your own development and differentiation as a scientist.

I referred to Michel Sadel's "Justice" course as an example of a course that is run by posing questions to stimulate critical thinking. For those of you who are not familiar with his lecture style, here is a link to his lecture series "Justice".
