Provide a 4 pages analysis while answering the following question: Diffusion and Osmosis. Prepare this assignment according to the guidelines found in the APA Style Guide. An abstract is required. One particular example is the absorption of water and other nutrients from the soil by root hairs in plants. The following experiments demonstrate these basic concepts in action, and how distribution of substances in two regions with different concenration gradients occurs.

In order to determine osmolarity of a potato and how it is effected by the process of diffusion, a simple experiment is performed. 7 cylindars are carved out from a potato, and then cut to a uniform size of 5 cm. One very important aspect of this experiment are the 6 sucrose solutions, ranging from 0.1 to 0.6 molars, 100 ml each, and placed separately in 6 250-ml beakers together with 100 ml of distilled water. A sensitive balance is also necessary to accurately determine the weight of each potato piece, before and after incubation.

Another experiment is performed to determine the process of osmosis. For this experiment a 500 ml beaker is used which is filled with 300 ml of water. A 25-30 cm dialysis tubing bag is essential, since it represents the semi-permiable membrane that is present during osmosis. 4 ml of a 30% glucose and starch (placed in the dialysis bag) and a small amount I2KI represent diffusing substances. Benedict’s reagent is also necessary to determine the diffusion pattern of the substances involved.
