Introduction The movement of water molecules across a semi-permeable membrane is the process of osmosis. If there is a solute and a solvent‚ each containing different concentration levels‚ then the water would move along its concentration gradient until each side of the membrane are equal. The water moves because the membrane is impermeable to the solute and the solute concentrations may differ on either side of the membrane. Water molecules may move in and out of the cell‚ but there is no net diffusion

The Elephants were playing against the ants in a soccer game. It was a close match‚ but when the ants’ star player dribbled the ball towards the goal‚ an elephant defender ran towards him‚ stepped on him and killed him. “What did you do that for!!” asked the referee. “I didn’t mean to kill him‚” said the elephant. “I was only trying to trip him up.” An ant and an elephant shared a night of passion but in the morning the ant woke up to find the elephant

Potato Osmosis and Diffusion Lab Report Emily Cocq Research Question: Will there be a difference in the experimented potato cores after being subjected to high concentrations of sugar? Introduction: Water can move through protein channels in cell membrane/cell walls. The water will move due to the water potential of the cells. If there is a greater concentration of solutes (chemicals) inside the cell than outside the cell and the chemicals can not move‚ then water will respond by moving

Diffusion and Osmosis Diffusion -the process by which molecules spread from areas of high concentratiion‚ to areas of low concentration. When the molecules are even throughout a space - it is called EQUILIBRIUM DIFFUSION Concentration gradient - a difference between concentrations in a space. Molecules will always move down the concentration gradient‚ toward areas of lesser concentration. Think of food coloring that spreads out in a glass of water‚ or air freshener sprayed in a room

Hands On Approach to Diffusion and Osmosis Abstract A. Plant and Animal Cell Diffusion and Osmosis In this experiment we observed carmine powder to better understand the concept of Brownian motion and the role of molecular movement in diffusion. The particles continuously moved in a completely random fashion‚ and the smaller particles moved with more speed than the larger particles. B. Potato Core Experiment In this experiment we estimated the osmolarity of potato tuber tissue

A cylinder is a shape with a circular bottom at the both ends that kind of looks like a pringles potato chip bottle THE formula of finding the volume of a cylinder is base area times height of cylinder. The base area will be the area of the circle which is pi x radius x radius So you just take that answer and multiply it by the height of a cylinder. done math math math cylinder cylinder asdfghjk lkjhgh jhgf ghjxskdskdgc kdshfkhshfkshksskkkkjs wordlimit mine is

in weight and volume when plant cells are incubated in OAS solution of known molarity. Estimated osmolarity of plant cells is the molarity of solution at which weight or volume of the plant cells does not change‚ means there is no net loss or gain of water. Introduction This study shares the results of an effort to understand diffusion and osmosis in general. It focused more into osmosis in plants cell‚ and how to indirectly measure osmolarity in potato tuber tissue. Osmosis is the diffusion

The Prince of Glory and The Eastern Front‚ both display the the conditions of both countries‚ soldiers‚ home front‚ and leadership within the battles of World War I. The differences between the two countries approaches to the war are vastly different‚ however‚ the themes within the battles are similar. These themes include the leadership of both armies‚ patience‚ and the home front stability; these themes found in both countries affect their outcomes of their battles. It appears that the French‚

The purpose of this experiment is to observe the osmosis reaction in a potato with salt and water. In cooking cooks will soak their cut potato’s in water if they will not use them immediately. This allows the potato’s to be used later without turning color. The experiment shows the flow of water through the membranes of the potato with salt over a period of four hours. II. Objective: The reaction of the potato to the side submerged in water and the half excavated with salt. III. Raw Materials:
