I finally flipped as another student complained about studying plants. I made this in retaliation and then realised that a lot of the images could provide useful discussion prompters. Feel free to use.
I do feel a bit freaked out by copyright issues here - I intended this for use on our school's password-protected VLE, and have only chosen to post it here and not on YouTube etc. Am I being paranoid?
Thanks to Stacey Baker for her "Darwin Day" video which inspired me on this course of action.
