I have found another website that you will love or hate. Personally, I think it is fabulous. The site is www.cellsalive.com and has cartoon animation of mitosis and meiosis, tumour development and more relevant to A2, interactions between different cells during the immune response. There is a lot of text on the site, but the little video clips are worth finding and watching. What else do you have to do on a cold November afternoon? Play and enjoy.
