Essay Title Rating
The Potato Chip Investigation.
Not rated
The predictions for the rate of reaction, between the Hydrogen Peroxide and the potato.
Not rated
The purpose of my investigation is to find out the concentration of the cell sap in potato cells.
Not rated
The purpose of this investigation is to test the movement of water into and out of potatoes from different strengths of sucrose solution via osmosis.
Not rated
The purpose of this investigation was to test how the enzyme catalase is affected by changes in pH and temperature.
Not rated
The rate at which substrate is converted into product during an enzyme-controlled reaction
Not rated
The Relationship between turgidity of potato cells and the concentration of surrounding medium
Not rated
The relationship between turgidity of potato cells and the concentration of the surrounding medium
Not rated
The target of this experiment is to determine the effects of varying temperatures on a specific enzyme, we will carry out some simple experiments using the substrate hydrogen peroxide throughthought the experiment.
Not rated
There are also other factors involved, these are:
3.5 out of 5 stars
There was one day of the year that David hated that day was sports day
Not rated
This is an investigation to determine how changing different sucrose solution will change the effect of osmosis in a potato cell.
Not rated
This is an investigation to show how the surface area of a potato affects the breakdown of hydrogen peroxide.
Not rated
This is decomposition reaction because the H O is breaking down to simpler H O + O H O forms in cells this is toxic and must be removed rapidly. Catalyse catalyses the breakdown in cells. Potato cells contain catalyse enzymes.
Not rated
This means that when the water concentration is lower in the tissue, the water will move into the tissue, and the potato will gain weight.
Not rated
Throughout this coursework I will be looking into and experimenting Osmosis. Which will be present in the potato cells, which I am using as part of my experiment.
Not rated
Title: An investigation into the affect of different concentration salt solutions on potato tissue

To analyse the effect that different strengths of sugar solution had on osmosis.
Not rated
To create an isotonic solution that potatoes can be stored in.
Not rated
To demonstrate the Water Potential of Potato Cells.
1.5 out of 5 stars
To determine concentration of cell sap in potato tuber cells.
Not rated
To determine if the increase of surface area of a potato will increase the amount of gas given off, when combined with hydro peroxide.
Not rated
To determine the concentration inside potato cells.
3.5 out of 5 stars
To determine the concentration of the cell sap in potato storage tissue. By using Osmosis, determine what the sugar concentration of cell sap is.
Not rated
