Factors Affecting the Movement of Water Through Osmosis
Factors affecting the movement of water through osmosis
Introduction
In this I will be investigating what effects the movement of water through osmosis. Osmosis is the diffusion of water. It is the process in which fluids pass through a partially-permeable membrane. It is the movement of water from high water concentration to low water concentration. Plant cells react to osmosis by hypertonic, isotonic and hypotonic.
Keywords
Hypertonic – is when the water outside of the cell is lower than that inside.
Isotonic – is when the net movement is the same in both directions.
Hypotonic – is when the water potential outside the cell is higher. Therefore the water has moved into the cell and the cytoplasm is pushing against the cell wall and the cell has become turgid.

Water Potential is when the water molecules in a system have a tendency to move from one place to another, it is usually represented by the Greek letter Ψ (Psi). Water potential is caused by osmosis.
Water potential (Ψ) is calculated by using the following equation:
Pressure potential (Ψp) + Solute potential (Ψs)
Factors that affect the movement of water * Concentration – As the water molecules will move from a high concentration of water to a low concentration of water. * Temperature – The hotter the temperature is the faster osmosis will take place as the particles will move more.
Chosen Factor – Sugar Concentration
In this investigation, I will be monitoring the effect sugar concentration has on the movement of water.
My hypothesis is: By changing the concentration of sugar, I think that the water will move from a high water concentration to a low concentration via osmosis. I predict that the more sugar concentration there is, the rate of osmosis will increase and therefore will have an effect on the results of the experiment.
