Biology Hl lab report: Topic: Osmosis of potatoes in different sucrose solutions. The aim of this experiment is to test whether more water moves out of a potato when it is placed in a sweeter sucrose solution than a potato in a less sweet solution. The hypothesis of the experiment is that we expect more water to move out of the potato placed in the sweet solution than the potato placed in a less sweet solution. Independent variable: concentration of sucrose‚ concentrations: pure water

Investigating the Osmosis Effect in Potato Cores Aim The aim of this experiment is to investigate the osmosis effect in potato cores while they are submerged in different concentrations of sucrose solution. Osmosis will take place while the potatoes are fully submerged in the sucrose solution. Apparatus æ Scalpel (1) æ Tile (1) æ Pr.

Martina Oganesyan Title of investigation: The effect of solute concentration on osmosis in potatoes. Research question: What is the solute concentration of a potato? Hypothesis: Osmosis is the movement of water across the membrane from an area of high concentration to an area of low concentration. The osmosis continues until the solute concentrations are equal in both areas. In this experiment‚ we put pieces of potatoes into test tubes with sugar solutions of different concentrations and leave

Stacy Hernandez Period 1 Mrs. Riley AP Biology Osmosis and Diffusion Lab I. Introduction: Diffusion is vital to many life functions of a cell‚ it allow the transportation of vitally important nutrients and compounds without the expenditure of excess metabolic energy. To explain diffusion‚ it is as if a bottle of perfume is opened at one end of the room‚ then in a short amount of time a person at the other end of the room can detect the scent of the perfume; this is the process of diffusion
