Summary Introduction
To determine: The result to be expected if a rat was fed lanthanum and then a sample of a cell layer in the digestive tract was observed under an electron microscope.
Introduction: In a multicellular organism, cells are linked to each other by specialized structures called cell junctions. Three types of junctions are found between cells in animals namely anchoring junctions, tight junctions and gap junctions.

MAIN IDEA: Eukaryotic cells have an extensive and dynamic framework called a cyto-
skeleton. The cytoskeleton is used for cell shape, internal structure, movement, and cell
division. Many cells are surrounded by and supported by a complex extracellular matrix and
are able to interact with adjacent cells and the environment via cell junctions.
5. List three common components of microtubules and microfilaments.

You prepare 5 mL solutions of salt dissolved in pure water at 0, 0.9, 1.5, and 5% NaCl. You have another solution of red blood cells, and you gently mix it and then add 100 uL of it to each of the three 5 mL solutions. You gently mix and observe a sample of each under the microscope. Results: Red blood cells look intact and normal in the 0.9% solution. In the 1.5% solution cells are present but look shriveled. In the 0 and 5% NaCl solutions, you do not see any cells at all!

The cellular membrane is critical to the maintenance of homeostasis in living organisms. The cell membrane separates the cell from the external environment and plays a critical role in regulating movement of material in and out of the cell. Additionally, eukaryotic cells are made complex by the presence of internal membranes that form organelles, so the cells may become specialized. These organelle membranes create compartments within the cell that can do specific functions. For this exercise, you will work in groups of four to progress through the activities. At the end of each activity, one group (chosen at random) will share how they responded and open the floor for further discussion.
