CHECK THESE SAMPLES OF The Effect of Osmosis on Potato Tissue When Placed In Different Concentrations of Sugar Solutions
The cell and its extracellular environments are fluid in that concentrations of substances dissolved in it vary.... To accomplish this, the cell utilizes the processes of osmosis and diffusion as appropriate.... This experiment has been designed to prove the hypothesis of the mechanisms of osmosis and diffusion through such a semipermeable membrane.... Physical movement of water occurs in both of these processes depending on the physical characteristics of the solutions that are being exchanged....

4 ml of a 30% glucose and starch (placed in the dialysis bag) and a small amount I2KI represent diffusing substances.... Then, 300 ml of distiled water is placed in a 500 ml beaker in which a small amount of I2KI is added.... The dialysis bag is placed in the beaker and they are left for 45 minutes.... placed in 3 different tubes, a small amount of Benedict's reagent is added to each tube.... Another experiment is performed to determine the process of osmosis....

ationale of the Test: Osmotic activity in the red cells is tested by adding increasingly hypotonic concentrations of saline solution to red cells.... As a result of osmosis, more and more water from the increasingly hypotonic solution will enter the red cells leading to increased volume of red cells by swelling.... If the concentration goes beyond threshold, more water will enter into the cells which already are at maximum volume for surface area, and will burst at the most hypotonic normal saline concentrations....

All experiments show qualitatively as well as quantitatively that the processes of diffusion and osmosis take place across concentration gradients until a state of equilibrium is reached.... Two of the processes by which such exchanges take place are known as diffusion and osmosis.... osmosis too is also a movement of components within a solution either from a higher gradient to a lower one or selectively under active transport systems controlled by cellular physiology, but this diffusion occurs across a semi-permeable membrane such as the plant cell wall or the animal plasma membrane....
