Observing osmosis‚ plasmoylsis and turgor in plant cells Investigation * Get a single layer of plant cells. If you are using red onion‚ cut a 1 cm square from a fleshy piece of onion and then peel off a single layer of the red cells. If you are using rhubarb‚ peel a piece from the epidermis. If you are using toadflax peel a piece of the lower epidermis of a leaf. * Place the strip on a slide and cover it with a drop or two of distilled water. Add a cover slip. * Look at the cells through

AP Biology August 23‚ 2012 Egg Osmosis Lab Definition of osmosis: The diffusion of water across a selectively permeable membrane from high to low concentrations Hypothesis: If I place an egg in vinegar‚ then the outer layer of the egg is going to become slimy and look like rubber. It will also become larger and bubbles will form on and around the egg. Hypothesis: If I place an egg in corn syrup‚ then the egg will become small and the outer layer will not look like rubber any longer. Day one:

Intertwined in the stories of “Gwilan’s Harp” by Ursula K. LeGuin‚ “The Washwoman” by Isaac Singer‚ and “The Last Leaf” by O. Henry‚ lays a burden of loss. All of these stories experience the greatest loss when a character dies. Torm‚ Gwilan’s faithful husband in “Gwilan’s Harp”‚ a humble‚ hardworking washwoman from “The Washwoman”‚ and Behrman‚ the unsuccessful artist from “The Last Leaf”‚ all perish in their stories. The characters that die impact the other characters in the story in different ways

Biology Lab #1: Chemical Diffusion Purpose To discover how the size of a cell affects the diffusion of chemicals throughout the cell. Hypothesis I predict that as the cell size increases the diffusion depth and the diffusion rate will decrease. Equipment • Eye protection • 250 mL beaker • Timing device • Scoopula • Ruler • Scalpel • Sodium hydroxide solution • 3 different sized cubes of phenolphthalein agar • Paper towels Purpose

The relationship between shape and diffusion rate Aim- To investigate the relationship between the shape of an object and the time taken for a substance to diffuse to its centre. Hypotheses- Part A) The 5x5x2.5mm block will turn clear first as the Surface area to volume ratio is high and the 10x10x10mm block will take the longest to completely diffuse the Acid to its centre. Part B) The flat‚ rectangular block will be the first to completely turn clear due to its high Surface Area/Volume Ratio

Laboratory Report on Urine Examination Introduction: When testing urine the test results may provide information regarding the status of carbohydrate metabolism and kidney function. The kidney glomeruli act as ultrafilters for the plasma protein; however as much as 150 mg/dl of protein may normally be excreted into the urine. In glomerular proteinuria‚ an increase in glomerular permeability occurs‚ resulting in an increase of urine proteins. High urine protein concentration therefore may indicate

The cells in the solutions of 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
