I selected the site to use as an example of using ecosystem modeling to teach a scientific technique. An interesting interactive program of Plant cell anatomy. Features include cutting, zooming, showing in 3-D just by clicking on the cell. Selecting electron micrographs of cell structures is also possible. I would rate this an excellent site on cell biology.
Text accompanies each cell structure.
This would be a valuable tool for students to learn about plant cell structures and functions by directly interacting with the computer screen . This site allows students to design and carry out genetic crosses of fruit flies that carry mutations and be able to visualize the results of the cross. This lab lets all aspects of Mendelian genetics to be carried out in the classes. Use in place of the AP Biology genetics lab. This site is very detailed as a text resource.
