The beakers were labeled accordingly, and then 20 g, 40 g, and 80 g (respectively) of table sugar was weighed out using a digital scale and placed into the corresponding beakers.

In addition, the size of the particles can affect the rate of diffusion through the membrane. In the experiment, the sucrose molecules are too large to pass through the dialysis bags while the water molecules are easily able to move freely in and out due to their small size.Whereas Osmosis is the process in which water crosses membranes from regions of high water concentration to areas with low water concentration.While molecules in diffusion move down a concentration gradient, molecules during osmosis both move down a concentration gradient as well as across it.Water molecules move from areas of a higher concentration to a lower concentration to move down their concentration gradient.Because of this, the water molecules will move at a faster rate during osmosis and diffusion.Osmosis 2 OSMOSIS INTRODUCTION: By definition, osmosis is the diffusion, or dispersion, of water through a selectively permeable membrane from a higher concentration to a lower concentration (Campbell, pg.132).There are many different factors that can affect the rate of osmosis such as temperature, particle size, and the size of the concentration gradient.Both diffusion, and osmosis are types of passive transport, which do not require help.When the concentration of the environment outside of the cell is lower than the inside Results The potato cores started to decrease in weight as the molarity went up.The results illustrated that increased concentration gradient increases the rate of diffusion of water in the tubes.We concluded that as concentration of the The following hypothesis was made in regard to effect of the concentration gradient on the rate of diffusion: The higher the concentration gradient, the faster the rate of diffusion.
