42. Describe the function of the following parts of a cell: nucleus, rough endoplasmic reticulum, smooth endoplasmic reticulum, golgi apparatus, ribosome, lysosome, plasma membrane, cytosol. 43. Name 4 structures present in a plant cell that are not in an animal cell and describe the function of 2 of them. 44. Formulate a hypothesis based on the observation that your car wouldn't start this morning. Your hypothesis should offer an explanation of why that is the case. Then offer a way you could test your hypothesis.
