How do different concentrations of salt solutions affect the mass of the potato after the process of osmosis?

St tellgy For this coursework, I provide be investigating the hobby point: How do different ingresss of season sources dissemble the cud of the white spud after the process of osmosis? Osmosis is the movement of weewee system particles from a soaring concentration of peeing particles to a low concentration crosswise a partially receptive membrane. A partially pervious membrane is a membrane that acts as a barricade to some molecules but allows others to freely diffuse by dint of. The partially semipermeable membrane of cubicle membranes prevent large molecules such as Sucrose, protein and starch to decease through but allow littler molecules such as oxygen, carbon dioxide and piss, glucose and amino acids to proceed. In this coursework we result be exploitation spud to test the rate of osmosis. If the battleground close to a electric cell has a higher urine concentration it will gain water by osmosis. This is because the water molecules surrounding the potato cell are able to pass freely crosswise the cell membrane in two directions; therefore more(prenominal) water will enter the potato than will withdraw from it so it will swell up. Furthermore, if the plain around the potatos cells has a lower concentration of water than the cell will loose water by osmosis due to more water diffusing out through the partially permeable membrane than entering the cell, this will go forth to a reduction in the size of the cell.

When the concentration of water molecules in the potato is near equal to that of the area around it, the rate of osmosis will decline and the cell will carry on the sam! e size, as there is an equal amount of water entering the cell than there is leaving it. Below is a drawn diagram showing the process of osmosis. Initial system later researching osmosis, I am now clear on the factors that my affect my results. These include, the size of the potato (weight), the concentration of the table salt solution (water, salt ratio), the time the potato is left in the salt solution.
