Lab 2: Thin-Layer Chromatography Abstract: In the TLC lab, TLC plates are used to experimentally approximate molecular weight and compare weights through Rf values. Different molecular components of each solution tested have a general distance that they will travel on the plate that depends on...
Experimental Lab 5: Diffusion and Osmosis Introduction In order for cells to maintain homeostasis, they must allow substances to move in and out of the cell. There are four different ways in which substances move across differentially permeable biological membranes, including simple diffusion, facilitated diffusion,...
DIFFUSION AND OSMOSIS Introduction It is important for the cell to have a way to separate the cytoplasm (inside of the cell) from the extra cellular materials (outside of the cell). This is accomplished by the cellular, or plasma, membrane. The plasma membrane is composed...
