As thy Days...

While the rest of the kids were making pizza maps of Europe, from the same materials Peter was developing an animal cell model as an extra credit project for his biology class. To better display the organelles, Peter left off cheese until the last minute.

Key:
Cytoplasm = pizza crust
Lysosome = pineapple
Golgi body = onion
Chromatin = peanuts
Nucleus = ham
Nucleolus = orange cheese
Centrioles = pepperoni
Plasma membrane = crust border
Smooth endoplasmic reticulum = spinach
Rough endoplasmic reticulum = spinach + sausage
Ribosomes = sausage
Mitochondria = mushrooms
