Osmosis rates in artificial cells daniel george department of biology grand valley state university 1 campus drive allendale, mi 49401 [email protected] abstract the lab for this paper was conducted for the topic of osmosis, the movement of water from high to low concentration.
Osmosis is the diffusion of water from a high concentration to a low concentration and water was the variable being tested in this activity because it is what made the mass increase for every sucrose solution.

Course summary biology 101: intro to biology has been evaluated and recommended for 3 semester hours and may be transferred to over 2,000 colleges and universities. The ability of an extracellular solution to make water move into or out of a cell by osmosis is know as its tonicity a solution's tonicity is related to its osmolarity , which is the total concentration of all solutes in the solution. 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. The cells will be hypertonic to the water, which is hypotonic, and the cells will gain water from the environment cells w/o a cell wall have a structure called a contractile vacuole which collects excess water and pumps it back out of the cell.
