  • Osmosis

    Measuring the water concentration of cell sap using plant tissue. Aim The aim of this experiment was to determine the concentration of sucrose solution which has equivalent water concentration to the plant cell sap. This means I will put the potato pieces in different solutions of different concentrations...

  • Osmosis

    Osmosis is the movement of water from an area of high concentration to an area of low concentration across a semi permeable membrane. An osmotic system is established when a semi-permeable membrane is placed between two solutions. In this biological systems context, osmosis is the exchange of water...

    both sides) Red blood cells are bound by a membrane which allows water to pass through while generally restricting the solutes. This process, called osmosis, causes cells to shrink due to loss of water when placed in hypertonic solution. On the other hand, red blood cells absorb water (called endosmosis)...

    Abstract: Osmosis is the transport of water across a selectively permeable membrane from a region of a higher water chemical potential to a region of lower water chemical potential. (Tzahi 2006) To demonstrate osmosis lab, artificial cells were made with various sucrose concentrations and were placed...
