It turns out that I am not the only person in the world to have crocheted a model cell. But I will almost certainly be the only person taking one to work on Monday to teach cell structure to S3!
Plant cell (left) Brown=cell wall, yellow=cell membrane, white=cytoplasm, green=chloroplasts, purple=mitochondria, turquoise=ribosomes, mauve=nucleus, pink=vacuole.
Animal cell (right) Yellow=cell membrane, white=cytoplasm, purple=mitochondria, turquoise=ribosomes, mauve=nucleus.
