You would now find that the potato in the fresh water would have swell due to the high concentration of the water outside the potato, which would travel into the potato (cytosis) while the potato in the salt solution would shrink due to the low. Then you feel the texture of the potato. It should have a different texture than before. The potato in the fresh water would now be hard and stiff while the potato in the salt solution would feel soft and bendy. The potato in the fresh water would now have grown a bit whether in length or width and the potato in the salt solution now would have shrank a bit whether in length or width. Result: First texture, final texture, first length, estate final. Flame test Lab Report Free essays 1 -.

Title: Effects of Osmosis, aim: to observe the reviews effects of high and low concentration of a potato. Apparatus: two glass containers, two potato strips measuring 3x1 cm, two beakers one of which would contain fresh water and the other would contain a salt solution, a ruler and a stop watch. Method: First you must already have your potato strips measuring 3x1 cm, place one of each potato in each of the containers. Ensure to feel the texture of the potatoes and observe the size of them. You would now pour in your salt solution in one of the containers and the fresh water in the other. After general doing that, let the potatoes remain there and calculate 30-45 minutes on your stop watch. After the time is up, observe the two potatoes texture and size.

If the concentration of water is not equal across a potato cell membrane (concentration of water outside the sell is more or less than.9) osmosis tends to occur. Water will move osmotically to regions of greater solute concentration (from hypotonic to hypertonic solutions). If water concentration outside and inside the cell is equal water shows no net osmotic movement from one to the other isotonic solutions. The experiment can be improved: Firstly by drying potato from water outside the potato. Secondly by using scales which have more accuracy.

Determining the water Potential of Potato tuber Cells

Make up four solutions of salt ( 0 1 2 3). Weight the plug sets. Place plug sets into each solution and continue to measure or weight them at specified time intervals. Report mean values only fo measurements or weights. Determine the percent change in lenght or weight for the potato in each solution. Calculate the exact percent of salt in the potato cell from the graphed data.

Salt, solutions, initial weight (g weight of plug sets after some time: mean percentage change in weight 12 min. - -20 we cant compare the changes in weight using grams because each plug set had different initial weight. Conclusion and evaluation: From the graphed data the percent of salt in the potato cell.1. The original potato cell concentration.9. The error could be because the water outside potato has influence on weight and not accurate measurement of mass by not exact scales which showed only one report decimal place.

Hypothesis: Potato cells in 0 solution of salt will swell. Potato will gain weight because net movement of water will be into the cells. Water moves down the concentration gradient. Potato cells in 2 and 3 solutions will shrink. Water moves out of the cells to regions of greater solute concentration.

Potato cells in 1 solution will change little in cell size or shape. The difference between solution concentration and potato concentration is small. So there is no big movement of water. Materials: Knife potato 4 salt solutions ( 0 1 2 3) paper razor blade. Method: Cut 12 plugs from similar potatoes. Remove the ends of each plug and skin.

Last, isotonic is when both solutions are equal to each other. My last definition comes about from water molecules movement. When they move, they go from the inside of the cell to an outside environment; this is called plasmolysis. All of these definitions are important to molecular movement and all interact with each other in one way or another. Introduction: Osmosis is a net essays diffusion of water between two solutions that differ in solute concentration and that are separated by a selectively permeable membrane. Hypertonic solution higher solute concentration outside the cell. Hypotonic solution lower solute concentration outside the cell. Isotonic solution have the same solute concentration outside and inside the cell.

Osmosis Rubric, passive transport means that it is a natural process of diffusion and it does not need any extra energy from a cell. Active transport is the opposite in that energy is needed from a cell. Osmosis is brought into this because it is the movement of water molecules. When observed, there are two types to a solution: solute and solvent. The solute is a dissolved substance and the solvent is when the solute is dissolved. When you have more than one solution, you compare them to see if they are hypotonic, hypertonic, or isotonic. Hypotonic is when the other solution in comparison short to the solution you are looking at is less solute. Hypertonic is explained as when one solution is more solute than the other.

number or concentration to an area of where they are less concentrated. Diffusion is important because it makes it possible for the random movement of molecules. After the diffusion process comes along two different types of transports; one is passive and one is active. We will write a custom essay sample.

It is a serious matter, not a fun little game. When a membrane is selective it chooses what salon it wants. Few things are moved through, not lots and lots. All of this moving is called diffusion. It is the net movement of molecules, there is no confusion. There are two types of transport: passive and active. Passive needs no energy where as active is reactive. Diffusion and Osmosis are important to know. Having such knowledge will make your brain grow!

Water molecules move from high to low. Osmosis is what they seem to know. Solute and Solvent are whats inside. The polarity of water makes it easy to find. Hyper and Hypo tells you biography how much is there. But isotonic means that they are fair. Water molecules move from the inside out. Scientists call this plasmolysis without a doubt. All of this happens inside a membrane.
