distilled water‚ 0.4% NaCl‚ and 0.9% NaCl would all appear to be inflated and could burst. This is due to the fact that the solution is hypotonic to the potato‚ thus water is entering the cell. Meanwhile‚ the cells in the solutions 5% NaCl and 10% NaCl would have shriveled cells. This is because the solution is hypertonic and water is leaving the potato out into the solution.

JavaArray An array is a container object that holds a fixed number of values of a single type. The length of an array is established when the array is created. After creation‚ its length is fixed. You have seen an example of arrays already‚ in the main method of the "Hello World!" application. This section discusses arrays in greater detail. An array of 10 elements. Each item in an array is called an element‚ and each element is accessed by its numerical index. As shown in the preceding

TOY: MR. POTATO HEAD! Since the time of my childhood I have been exposed to hundreds of toys and games. However‚ only a few stand out in my memory and even fewer still remain in my possession today. There are many toys in America‚ which are known by all ages‚ nationalities‚ and social classes. Toys such as Barbie‚ Legos‚ Cabbage Patch Kids‚ GI Joe‚ and many more are well known commodities‚ which have been in existence since before my time. Although there are numerous toys I can remember

Aim The aim is to find the concentration (mole/dm3 (M)) of solute in a potato cell by using the process of osmosis and different concentrations of sucrose solution. Background information Osmosis is diffusion of water across a partially permeable membrane. It moves from a solution with less solute concentration (high water potential) to a solution with more solute concentration (low water potential). The one with a high water concentration is called a hypotonic solution and the low water concentration

Experiment: Turgor in Potato Tissue 1. We labelled three test tubes A‚ B‚ C‚ D and added initials of people in our group. 2. Used a syringe or graduated pipette to put 20 cm3water in tube A and 10 cm3 in tube B. 3. Put 20 cm3 of 17% solution in tube C and 10 cm3 in tube B; put 20 cm3 pure sucrose solutions in tube D. 4. Working on the dissecting board I cut the ends off large potato. I was careful with the knife and cut it onto the dissecting board away from myself. 5. Used a cork

Lab Topic: Movement of Materials Across the Cell Membrane—Potato Tuber Cells Introduction: Osmosis is a form of diffusion in which water diffuses through a selectively permeable membrane from a region of high concentration to a region of lower concentration. This form of diffusion takes place when the molecules in high concentration are too large to move through the membrane. Three factors that determine cell membrane permeability are shape‚ size‚ and polarity. For this experiment‚ it must
