1.1 Introduction to Cells
Essential Biology 2.1: Cell Theory
And the wikipedia page
And C4B page
And the brilliant Amazing Cells resource from Learn.Genetics at Utah.
Microscopy & Evidence for Cell Theory
Get the awesome free Virtual Electron Microscope, or send off some samples to be scanned for nowt, from here or here.
Evolution of the cell, from Learn.Genetics
The slow death of spontaneous generation, from Access Excellence
A newly developed Mesolens combines the best of both worlds (light and electron microscopes), with the ability to view thousands of living cells and their contents at the same time.
Size of cells:
Here’s a page of animations about techniques in microscopy
SA:Vol ratio from Wikipedia
And some cool animations to put things in perspective:
From Learn.Genetics at Utah (best one) or this one from Cells Alive.
The fairy wasp is smaller than an amoeba, from Ed Yong
Here’s another teacher explaining how to calculate magnification using questions from one of my Essential Biology sheets:
Stem Cell Differentiation (animation) from MCB Harvard
Cell differentiation video from Teachers Domain
Start with this: A Stem Cell Story, from EuroStemCell:
Stem Cells animated tutorial from Discover Biology
StemCells: Seeds of Hope? video from Teachers Domain
Animation: Human embryonic stem cells, from Sumanas
Animation: Creating human embryonic stem cell lines, from HHMI
NewScientist special reports on Stem Cells
Great Stem Cell videos from Eurostemcell.org (look at who they quote as a reviewer! (this site used to be called Science Video Resources)
Stem Cells cribsheet from SEED Magazine
Get your head around this one: “Breast cells naturally transform into stem cells,” by Ed Yong. Is this a paradigm shift in progress?
Another form Ed Yong – “The genetic sergeants that keep stem cells stemmy” Read it again when you think about the central dogma of genetics.
Therapeutic Uses of Stem Cells
Animation: Stem cells & Therapeutic uses, from MCB Harvard
Animation Stem Cells transplants in lymphoma
Stem cells injected into brain of stroke patient – world first, Guardian
Stem cells used in spinal cord trial, from the Guardian
Sir Ian Wilmut, director of the MRC Centre for Regenerative Medicine at Edinburgh University, who led the team that created Dolly the sheep, said: “This is very exciting news, however, it is very important to appreciate that the objective of trials at this stage is to confirm first of all that no harm is done to patients, rather than to look for benefits. Once that has been confirmed then the focus moves on to development and assessment of the new treatment.“
How does Wilmut’s comment demonstrate the precautionary principle as applied to biotechnology?
Now, if you’re feeling advanced, here are the Stanford students with ‘regulatin’ genes’:
Embryonic Stem Cell Patents Banned in the EU

Thanks for using my image of Pasteur’s experiment on slide 6!
Thanks for producing it, Mike!
Love your site,
its good for the students. comprehensive type of learning
Have you seen this video for cells? I found it kind of cool.
This is cool – thanks for sharing!
Hi I can not open the powerpoint presentation on 2.1 cell theory???? everything else works… any ideas… please help
Neither can I – I don’t know why, as we are using it in class! Must be a SlideShare issue.
Where can I get the answers for the essential biology 02.1 Cell theory file? Thank you! Great help
I don’t have an answer key for these (I don’t use them very often), but most answers are in the links, presentations or on Click4Biology.
I was using one of your Cell Theory slides with my classes, and I think there is a typo on slide #12…shouldn’t it say “45mm” and not “450mm”? I’m a little math-slow sometimes, so maybe I’m missing something, but let me know if this is indeed an error. Thanks!
You’re right! Well spotted – thanks for letting me know. I’ll change it as soon as possible.
Your site is like, so awesome! I truly love it! Congratulations!!
