What I have learned - I have learned about cell membranes and how they function differently then a cell wall. The cell membrane allows for transportation of substances across the boundary where cell walls don't. There are three types of ways that substances can move through the membrane, either with a selectively permeable membrane which allows substances to pass easily, a passive transport where no energy is need to pass through the membrane or a facilitated diffusion where the substance are not all allowed to move through.
What I have found difficult - I don't quite understand osmosis in relation to water and being hypertonic or hypotonic. I am unable to understand the diffusion of water to really understand the way it works.
How does structure relate to function? - The structure of the a membrane allows for the membrane to carry out certain functions. If the protein was not embedded in the membrane the membrane wouldn't have the signals it needed to make sure the function of the membrane is properly working.
Hypertonic describes a solution in which the solute is less that the solution. For example, if we were to put 1 cup of gatorade powder into two cups of a water solution, the solution would be called hypertonic.
ReplyDeleteHypotonic describes just the opposite, instead there would be 2 cups gatorade powder and 1 cup of solution.
Osmosis simply describes the way that a solution may cross over a membrane, or in their example a solute. Not all of the solution may enter to be with the solute, osmosis simply states that.
Osmosis is a type of passive transport, which means the molecules move from high concentration to low concentration which is the same as hypertonic to hypotonic. The goal is for it to become isotonic, which is when both solutes are equal.
ReplyDeleteOsmosis is when water, the hypotonic solution, diffuses across the membrane to the hypertonic solution. Some molecules are unable to pass through the membrane so the concentrations try to become equal which is isotonic.

ReplyDeleteOsmosis is when water is diffused across a selectivley permeable membrane. This water is moved from a place with high concentration, to a placeo of a lower concentration. In an animal cell, the ideal state is the isotonic solution, because everything is equal.
