With all the webspace devoted to genetics and biotechnology at the moment, it’s great to stumble upon a site that is bringing ‘old school’ Science into the new millenium. Though no-one seems to call it botany any more!
The Plant and Soil Science eLibrary hosts a collection of animations on plant science topics and cell biology that are useful, clear and can be easily downloaded. They are all also available in Spanish and many have pdf help notes for students.
The site is designed primarily for people who wish to earn credit for further studies in crop science and contains such units as plant physiology, crop technology and nutrition technology. There’s even some genetics in there.
