More about these tools
In Name it a ring lights up and you choose or type the name. Study turns every label on, with a line on what each part does. Missed parts come back at the end of the round, and every drawing prints as a blank worksheet or as a labeled answer key.
Start with a whole cell: plant, animal or bacteria. Then move in closer. The nucleus, mitochondrion, chloroplast, Golgi apparatus and cell membrane each have a larger drawing that shows the inner parts that are too small to tap on a whole cell. The drawings were made for this site, and names and facts were checked against open college textbooks on the date each page shows.
