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

St regularisegy For this coursework, I provide be investigating the chase point: How do different ingresss of season roots dissemble the down of the white spud after the process of osmosis? Osmosis is the movement of piddle system particles from a soaring concentration of peeing particles to a low concentration crosswise a partially pervious 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 porous membrane of prison jail cell membranes prevent large molecules such as Sucrose, protein and starch to breathe out through but allow littler molecules such as oxygen, carbon dioxide and piss, glucose and amino acids to proceed. In this coursework we pull up stakes be using murphy to test the rate of osmosis. If the battleground close to a cell has a higher irrigate concentration it will gain water by osmosis. This is because the water mole cules surrounding the stump spud cell are able to pass freely crosswise the cell membrane in two directions; therefore more than(prenominal) water will enter the potato than will retire 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 car! ry on the same 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 method acting 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 salinity solution (water, salt ratio), the time the potato is left in the salt solution.
