What do you think would happen if digestive enzymes in a cell were NOT contained in lysosomes but floated freely around in the cytoplasm? 6. Some cells (muscle and sperm cells) have large numbers of mitochondria. Other cells have few mitochondria. Why is there a difference? (HINT: think about the function of the mitochondria). Prokaryotic vs. Eukaryotic Cells Cell wall Cell membrane You should also be familiar with the structure and function of the above structures found in prokaryotic & eukaryotic cells. Be able to pick out the different cells based on a picture. Know the kingdoms that belong in each category of cell too. Structure & Function Lab- review the structure and function difference of the 6 cells we labeled in the lab.
