Americas. One of the most important crops brought to the Old World was the potato. Potatoes, as a substitute for wheat or rice, provided peasants a new source of calories. Potato was originated South America and then introduced to the Old World; the crop also raised political, economic and social consequences, such as late blight, Irish Famine, and sudden population increase in China, from its production. Domesticated potatoes were once all belong to one botanical species, Solanum tuberosum; it included
Investigating Potatoes Introduction In this scientific investigation I am researching what has happened to Mr Davies's potatoes. During the winter storms a few years ago a sea wall protecting Mr Davies's potatoes was breached causing his land to flood. Mr Davies's is now worrying about his crop as it's producing a poor quality and low yield. I intend to explain to Mr Davies via the use of experiments
Osmosis in Potatoes Planning -------- Introduction: Osmosis is the special name used to describe the diffusion of water across a membrane, from a dilute solution to a more concentrated solution. In biology, this usually means the diffusion of water in and out of cells. Osmosis is just one special kind of diffusion because it is only water molecules we are considering. Molecules will diffuse from where there is a lot of them to a region where they are fewer in number; that is
Osmosis in Potatoes Aim: My aim in this experiment is to find out if osmosis occurs in a potato, and how it will affect the potato in different molar solutions of sucrose and water. Using the same size potato. Theory: Osmosis is the passage of water molecules from a weaker solution into a stronger solution, through a partially permeable membrane. The tiny holes in the membrane of the potatoes will allow the water molecules to pass through in and out of the solution and the potato
Investigation Of Osmosis In Potatoes Aim: To investigate the affect of different concentrations of sugar solution on potato cells. Variables: The variables are; the concentration of sugar in the solution and the mass of the potato cylinder. We will measure the mass of a potato cylinder after a certain amount of time in a certain solution. Fair test: To keep the test fair we need to keep the controls the same. Like keeping the temperature the same so the kinetic energy doesn't
Baked Potatoes or French Fries Is it ever a wonder that kids get away with eating the darndest things. They gobble candy ice pops, french fries and for the most part remain amazingly thin and fit. However, adults with the same type of diet are high-cholesterol dynamites just waiting for an explosion into triple-bypass heaven. Why do the little brats get to eat what ever they so desire without worry, while adults have to monitor every gram of anything that even considers passing through their lips
Investigating Osmosis in Potatoes Preliminary Experiment Aim The aim of this experiment is to determine the solute concentration of potato tissue; i.e. To investigate at which point the sucrose concentration is the same as the solute concentration inside the potato (an equilibrium is reached) Introduction Osmosis is the movement of water molecules from an area of high concentration; (a weak solution), to an area of low concentration; (a strong solution), through a partially permeable
Investigating Osmosis in Potatoes Aim: Investigate the movement of osmosis through a selectively permeable membrane, in this case potato. Introduction: Osmosis is the movement of water through a semi permeable membrane. The water passes from an area of high concentration to an area of low concentration, until the two concentrations are equal in concentrations of water. Many cell membranes behave as semi permeable membranes, and osmosis is a vital part in the movement of liquids
The Effect of Different Sugar Concentrations on Potatoes Aim: To investigate the effect of different sugar concentrations on potatoes. Osmosis is defined as the net movement of water molecules from a region in which they are highly concentrated to a region in which they are less concentrated. This movement must take place across a partially permeable membrane such as a cell wall, which lets smaller molecules such as water through but does not allow bigger molecules to pass through. The
The Effects of Different Salt Solutions on Potatoes Plan My aim is to investigate how different concentrations of salt solution affect the movement of water through a partially permeable membrane (osmosis) in potatoes. Osmosis is the movement of water from a high concentration to a low concentration through a partially permeable membrane. I will add pieces of potato to varying concentrations of salt solution, wait on each solution and then record the results. I will eventually use the
The Effect of Osmosis in Potatoes Aim: The aims of the experiment are: * To see whether different concentrations of sucrose solution (0%, 0.25%, 0.5%, 0.5%, 0.75%, 1%) have effects on the size and weight of cylinders of potato that are put into them. * Also I aim to find out which of the concentrations affect the potato cylinders in size and weight the most and the least. Prediction: I predict that the concentration which will affect the size an weight the least will be
Experiment to Investigate Osmosis in Potatoes The aim of this experiment is to investigate the movement of water in and out of plant cells. The cells chosen for study will be taken from potato tubers. Firstly I will explain what osmosis is. Osmosis is the passage of water from a region of high water concentration through a semi permeable membrane to a region of low water concentration. This definition contains three important statements: a) It is the passage of water through a semi permeable
Investigating Whether a Sugared Solution Has an Effect on Potatoes Osmosis is the passage of water molecules from a weaker solution into a stronger solution through a partially permeable membrane. In this case, Osmosis applies to our practical because we are trying to see if a sugared solution (sucrose) has an effect on potatoes. I aim to investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato chip
Investigating the Concentration of Sucrose in Cells of Carrots and Potatoes Plan Introduction Osmosis is defined as 'the net movement of water molecules from a region of high water concentration to a region of lower water concentration through a partially permeable membrane'. In my experiment the process of osmosis will be due to the concentration of sucrose inside the cell compared to outside. Therefore if there is a higher concentration of sucrose molecules outside the cell then
The Effect of Salt Solution Concentration On The Mass Of Potatoes Introduction ============ In my investigation to find out how salt solution concentration affect the mass of potatoes, I will investigate how much the mass of a potato changes if I leave it in a beaker of water with a specified salt concentration for half an hour. I will change the salt concentration after each experiment. Background Knowledge -------------------- Osmosis is the passage of water molecules from
The Effect of Solute Concentration on Osmosis in Potatoes AIM: to find out the effect of solute concentration on osmosis in potatoes. This is to find the equivalent osmotic potential. [IMAGE] PREDICTION: Osmosis is the movement of water particles from a high concentration to a low concentration through a partially permeable membrane. Osmosis happens when a partially permeable membrane allows small water particles to pass in or out towards a low water concentration. To reach an equivalent
Investigation of Factors Affect Osmosis in Potatoes Aim The aim of the following experiment was to investigate the effect of varying the concentration of sucrose solution on osmosis in a potato. Preliminary Experiments One preliminary experiment was done before the main experiment. From the preliminary, we were trying to find out how osmosis actually occurred in potatoes, and gave us a vague idea on what the main experiment would be like. This preliminary will aid my prediction

The New World would contribute to this, as potatoes and maize could withstand harsh weather conditions around the world. In times of hardships, these same crops proved to overcome famine. This would in turn be able to help families survive. Without such hardy crops, the world’s population would be
Investigating Osmosis in Potatoes at Different Concentrations of Sucrose Solutions Planning Aim: The aim of this experiment is to find out how solutions of different strength affect the osmotic movement. Preliminary work: For the preliminary work, I did a try out test to see if the method I had works. Also, I wanted to use the results I have after completing the experiment so that I can have an overview of how sucrose solutions of different strengths affect the diffusion of water
How Osmosis In Potatoes Is Affected By Solution Concentration Aim To investigate how the concentration of a salt and water solution affects the rate of osmosis in a potato. Osmosis Osmosis is the passage of water from an area of high water concentration to an area of lower water concentration, through a partially permeable membrane (a membrane which allows small molecules like oxygen, carbon dioxide, water, ammonia, glucose etc to pass through, but does not allow larger molecules
