Water Potential Of A Potato Tissue

- Introduction Aims of experiment Conduct one experiment to determine the water potential of a potato tissue. Conduct another experiment to determine the osmotic potential of an onion cell. Water in plants Water plays a critical role in plants as it makes up 85% to 95% of the plants’ weight and 5% to 10% of the seeds’ weight which makes it the most abundant complex in plant cells(1995). Water is also involved in organic compounds synthesis, support the plant(95). Reactions occur in water, and solvents move in the water(95)....   [tags: Cell wall, Osmosis, Cell, Plant cell]

Investigating Osmosis in Potato Tissue

- Investigating Osmosis in Potato Tissue Aim To estimate the concentration of sucrose in potato tissue. Hypothesis ========== I believe that the potato tissue that has been in the hypotonic (0.1M sucrose) solution will be more turgid than before, while the tissue in the isotonic (0.3M sucrose) will be similar to its previous state. The tissue that has been in the hypertonic (0.5M sucrose) should be far more placid than it was before. This is because of osmosis - water diffusing in and out of the potato tissue cells....   [tags: Papers]

Investigating Osmosis in Potato Tissue

- Investigating Osmosis in Potato Tissue Aim-We are going to investigate how 'osmosis' is effected by higher and lower concentrations of water using potato cylinders as selectively permeable membranes. A selectively permeable membrane is something only water molecules can pass through. We will cut eighteen potato cylinders to the same width and length using a scalpel and a corer on a white tile. We shall use the same potato for each cylinder. The cylinders should then be around the same mass....   [tags: Papers]

Osmosis into Potato Tissue

- Osmosis into Potato Tissue Aim: To investigate how varying the sucrose concentration around piece of potato tissue affects the diffusion of water (osmosis) into or out of the cell. Introduction: Definition of Osmosis: This is the diffusion of water molecules from an area of high water concentration (dilute solution) to an area of low water concentration (concentrated solution) through a permeable membrane. The rate, again, depends on the surface area, the concentration gradient and the properties of the partially permeable membrane....   [tags: Papers]

The Factors Affecting Osmosis in Potato Tissue

- The Factors Affecting Osmosis in Potato Tissue Planning In this coursework I am investigating the factors affecting osmosis in potato tissue. [IMAGE] 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 membrane, which lets smaller molecules such as water through but does not allow bigger molecules to pass through....   [tags: Papers]

Factors Affecting Osmosis in Potato Tissue

- Factors Affecting Osmosis in Potato Tissue Introduction: I am going to design and modify an experiment used to show osmosis in potato chips in different concentrations of sucrose solution. I am also going to investigate on how potato chips change in volume and weight when placed in different concentrations of sucrose solution. I will also conduct a preliminary experiment before my final experiment. Aim: To investigate the effect of different concentration of sucrose solution on potato chips....   [tags: Papers]

The Effect of Different Concentration of Salt Solutions on Potato Tissue

- The Effect of Different Concentration of Salt Solutions on Potato Tissue Title: An investigation into the affect of different concentration salt solutions on potato tissue Aim: .I have to find out the effect of varying salt concentrations on a potato tissue. Also to find out how osmosis occurs with different salt concentrations from very dilute to very concentrated. I will be looking for any changes in mass and length Prediction: I predict that the most concentrated salt solution (1 molar) will be the solution that will have the most dramatic effect upon the tissue of the potato....   [tags: Papers]

The Effect of Changing Solute Concentration on Osmosis in Potato Tissue

- The Effect of Changing Solute Concentration on Osmosis in Potato Tissue Aim The aim of the investigation is to find out the effect of changing solute concentration on osmosis in potato tissue. Prediction I predict that if the solute solution is more concentrated than the potato, the potato chip with the more water potential will lose water, so if the potato chip is placed into a dilute solute solution, the potato will gain water. Here's the example- if the original cells is 5g then and placed into a diluted solute solution the mass will raise to 7g....   [tags: Papers]

The Effect of Concentration of Sucrose Solution on Osmosis in Potato Tissue

- The Effect of Concentration of Sucrose Solution on Osmosis in Potato Tissue Aim:- To find the effect of varying external concentration of sucrose solution on osmosis in potato tissue. Variables:- J The concentration of the sucrose solution around the potato tissue. Depending on the concentration of the solution, osmosis will occur more or less. J The size and shape of the potato. The longer and wider the potato tissue, the larger the surface area, which means that more of the potato is exposed to the solution giving it more of a chance of osmosis occurring....   [tags: Papers]

The Effect of Water Concentration on the Mass of Potato Tissue

- The Effect of Water Concentration on the Mass of Potato Tissue Aim: The aim of this investigation is to discover the effect of water concentration on the mass of potato tissue, and also to investigate the movement of osmosis through potato tissue. Scientific Knowledge: When a substance such as a sugar dissolves in water, the sugar molecules attract some of the water molecules and stop them moving freely. This, in effect, reduces the concentration of water molecules. Water Potential: The water potential of a solution is a measure of whether it is likely to lose or gain water molecules from another solution....   [tags: Lab Report]
