Background: In this lab experiment, students were able to work with the concept concerning the osmosis ideology. This was observed through two different processes where plant and animal cells were utilized. In using these cells, the students were able to identify and experience how Osmosis works with osmotic concentration, osmotic potential, water potential, and osmotic pressure. All of these concepts and the properties of the cells let us make observations that would help piece the entirety of the experiment. Through this we saw how the process of osmosis occurs when the tendency of water to move from one place to another, (water potential) changes. Along with those observations one also visually comprehended that depending on the type of solute entering a cell, the environment could quickly transition from either a hypertonic, hypotonic, or isotonic solution. The ultimate purpose of the experiment was to understand the effects that solute…show more content…
Along with the blood the first tube had 1ml of 300mM of NaCl added to it, the second had 0.50mL of the 300mM NaCl solution added to it, and the third had 1.00mL of the same NaCl solution added as well. Along with the NaCl, the first tube had no distilled water, the second had 0.50mL of water and the third had 1.00mL. After gently swirling, tube number one had the lightest red color, the second was darker, and the third was the most opaque red. As mentioned in the beginning the vial with the most NaCl attracted the water to move towards it generating osmosis, and it is said that during osmosis water moves from a hypotonic solution into a hypertonic solution. This is due to the fact that the presence of dissolved solutes cause water to move from an area of low solute concentration to an area of higher concentration, and because osmosis is a passive process, water always moves from an area of greater water potential to an area of lower water
