To Determine The Water Potential Of Potato Tissue

Investigating the Water Potential of a Potato. I have been asked to investigate the water potential of a potato. During my investigation I will not actually be able to measure a value for, as it is a pressure value (kPa). Osmosis is a special form of diffusion involving only water molecules. It is defined as "The passage of water from a region of high water potential to a region of low water potential through a partially permeable membrane" Definition of Water Potential. The potential for water to move...

Investigating the Water Potential of Potato Cells

Investigating the Water Potential Of Potato Cells Aims 1. To test how water potential, in a solution, affects the movement of water in and out of a cell by osmosis Prediction I predict that by increasing the water potential around the outside of the potato cell, (i.e. so that the water potential is greater outside the cell compared to the inside of the cell e.g. 0m sucrose) that the net movement of water into the cell will increase. This is due to the water potential being greater outside the cell...

Water Potential: Lab Write Up

Abstract: Water potential is the measure of free energy of water in a solution. The purpose of this lab was to find the water potential of a potato cell. The problem of this lab was, if there was a high molarity of solute, would it have a positive or negative water potential? The hypothesis of the experiment was, if there is a high molarity of solute then the water potential would be lower or negative. After obtaining potatoes, we cut them into pieces, weighed them, and then placed them in a solution...

Water Potential and Osmosis

is the movement of water across a selectively permeable membrane. In osmosis, water diffuses across the area of lower solute concentration to that of higher solute concentration until the solute concentrations of the environment and the cell are equal. Tonicity, which is the ability of a solution to gain or lose water due to osmosis, results in an environment that is isotonic, hypertonic, or hypotonic. A hypotonic solution has a lower solute concentration than the cell so water moves into the cell...

If there is a higher solute concentration in the cell than outside the cell, the water will move into the cell. However, if the concentration of inside the cell is lower than the outside, water will not move into the cell. This process is called osmosis.

Effect of Osmosis on Potato

Effect of Osmosis on Potato Aim: To investigate the effect osmosis has on potato pieces that are placed in different concentrations of sugar solutions in water. Hypothesis: I believe that the more saturated the solution is the lighter the potato will be, and the potato in the clear water will weigh more after being left in the solution over a 24 hour period. This is because the cell membranes in the potato act as semi permeable membranes (meaning that they only allow certain molecules through)...

Osmosis in Potato Tubers

Osmosis in Potato Tubers Andrew Dickson Background When a plant cell is bathed in a solution of the same concentration (isotonic) as its intracellular environment, its mass and volume remain the same. This is because water enters and leaves the cells at the same rate. There is no net loss or gain of water by osmosis. Samples of cells can be placed in a range of solutions of different concentration. The cells will gain water by osmosis when placed in solutions which are more dilute (hypotonic)...

This is important because humans, animals, and plants all need water to survive. It is controlled by the sun, which produces energy in the form of heat. This heat energy causes the water in the world's oceans, lakes, etc. to warm and evaporate. As the water is heated, it changes its phase from liquid to gas.
