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

Eukaryotic & Prokaryotic Cells Introduction: The Cell: The cell is a functional unit of all living organisms. Cells have evolved into two fundamentally different types‚ eukaryotic and prokaryotic‚ which can be distinguished on the basis of their structure and the complexity of their organization. The simplest organisms which consist of one cell are called prokaryotes. More complex organisms are called eukaryotes and they consist of many cells. Objectives: * Define the terms: Eukaryotes
