Ap biology lab 1 - diffusion & osmosis paul andersen starts with a brief description of diffusion and osmosis he then describes the diffusion demonstration and how molecules move over time he then explains the concepts behind the osmosis lab and how potatoes are affected by increasing sucrose molarity. The purpose of the lab was to test out osmosis no, my results did not exactly support my hypothesis because the bag with 00 m of sucrose should have a change of mass of 0, but instead, there was still a change in mass (49%.

Ap bio lab #1 diffusion / osmosis bottom line: osmosis moves water from hypotonic to hypertonic the higher the original concentration in the dialysis bag, the more water that moves into the bag during the 30 minutes. Diffusion and osmosis are means of passive transport while diffusion is the process by which substances move from areas of high concentration to areas of low concentration to balance, osmosis is the diffusion of water through a semipermeable membrane.

Laboratory #4 - diffusion and osmosis (ap lab #1) ap biology overview: in this lab you will: 1 investigate the process of diffusion and osmosis in a model membrane system 2 investigate the effect of solute concentration on water potential as it relates to living plant tissues. In this ap lab, i learned more about diffusion and osmosis through the cell membrane and also through organisms and plants i also learned completely about water potential, what it is, and how it shows where water is moving (whether it is moving in or out of a cell or organism. Ap biology how would you explain the results you obtained which substances are entering the bag and which are leaving the bag support your answer with experimental results what evidence could have been collected to show quantitatively that water diffused into dialysis bag what results woudl you expect if the experiment started with a glucose and iki solution inside the bag and only starch. In this laboratory we use bars as the unit of measure for water potential 1 bar = approximately 1 atmosphere water potential the water potential of pure water in an open container is zero because there is no solute and the pressure in the container is zero adding solute lowers the water potential ap biology lab #1 osmosis and diffusion.
Lab 1 osmosis & diffusion osmosis lab introduction: cells have kinetic energy this causes the molecules of the cell to move around and bump into each other diffusion is one result of this molecular movement diffusion is the random movement of molecules from an area of higher concentration to areas of lower concentration osmosis.
