Diffusion And Osmosis Abstract In this Diffusion and Osmosis lab a total of three experiments were performed. For experiment 5.1 we investigate diffusion through a selectively permeable membrane and the many factors that influence the rates of diffusion.In experiment 5.2 we investigate both animal and plant cells in different molar solutions and the different osmotic behaviors within the cells.
This lab was about diffusion and osmosis, in this lab we tried to organize the experiment the best we could.. In addition, unfortunately we didn't read the lab properly that's why we made a major mistake in our procedure 2 where we were supposed to fill all the beakers with water but we did the opposite and filled the beakers with different solutions which affected our lab results.
Osmosis Lab 2. Explain your observations in detail in terms of concentration gradient, diffusion, osmosis, osmotic pressure, passive transport, and active transport. A. The osmosis lab was a really awesome lab. It gave you the excitement for three days to see how much the egg has changed.
This lab was to understand how diffusion and osmosis worked. The data that was received was consistent at some times. For part A and D of the lab, the results and calculations were consistent, but part B and C showed little consistency. That is because part B and C when comparing the percent change in mass with others, the numbers varied.
AP Biology 16 April 2013 Lab 1: Osmosis and Diffusion The purpose of this experiment is to decide which flasks correspond to the solute concentration of sucrose, which are 0.8M, 0.6M, 0.
Osmosis is crucial to the survival of an organism because it controls the balance of water between the cell and its surroundings. In order for simple diffusion and osmosis to happen, there must be a moist and permeable membrane and a concentration gradient to move down.
