1. Substances soluble in fat: fatty acid‚ glycerol‚ some vitamins (A‚D‚E‚K) 2. Neutral particles: water‚ oxygen‚ carbon dioxide‚ Example of Diffusion Between alveoli and blood capillaries in the lung during gases exchange. OSMOSIS What is Osmosis? Osmosis is the diffusion of a water through a semi-permeable membrane‚ from a solution of low solute concentration to a solution with high solute concentration. It is a physical process in which a solvent moves‚ without input of energy‚

We also can observe the actual structure of plant cells which consists of nucleus‚ vacuole‚ cytoplasm‚ cell wall etc. This experiment indicates the transport across membrane in plant cells when involving water through osmosis.

ACTIVITY 1 Simulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. __The size and the concentration. ___ 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? __ The molecules were to large to go through. My results matched._ 3. Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your

Some potatoes increased in mass while others decreased due to osmosis. Potatoes that had a higher concentration increased in mass because water passed through the membrane into the potato in an effort to dilute it. Potatoes that had a lower concentration than the solution decreased in mass because water flowed through

minutes and record your observations in the data table 5. While you are waiting‚ answer the questions. Questions: 1. Define diffusion – the movement of particles from an area of low concentration to an area of high concentration 2. Define osmosis - the movement of particles from low solute concentration to and area of high solute concentration across a semi-permeable membrane. 3. Why is iodine called an “indicator”? Iodine is called an indicator because it can detect the presence of

The results provide evidence that when there was an increase in the sodium chloride concentration the mass of the potato prisms declined. At the zero percent concentration there was an increase of mass by 1.75%‚ from there the 1%‚ 3%‚ 5% and 10% begun on a downward trend with the percentage change in mass declining. The graph was on a steady decline from 0% being the highest point with a change of mass of 1.75% finishing with the 10% solution on a decline of -12.28%. From observing the scatter plot
