The Onion Cell Lab Background: Onion tissue provides excellent cells to study under the microscope. The main cell structures are easy to see when viewed with the microscope at medium power. For example‚ you will observe a large circular nucleus in each cell‚ which contains the genetic material for the cell. In each nucleus‚ are round bodies called nucleoli. The nucleolus is an organelle‚ which synthesizes small bodies called ribosomes. Ribosomes are so small you cannot see them with the light microscope

Cell Transportation Lab Eggs are a great example of a cell. Underneath the hard shell is a thin membrane that is just like the cell membranes in your cells. There are microscopic pores in the membrane that allow substances to move in and out of the cell. Way Cool! Recall that the function of the cell membrane is to control the internal balance of the cell. It helps to maintain homeostasis. In this lab you will use vinegar‚ an acid‚ to dissolve the shell off of the egg to expose the membrane
