This portion of the lab is not done in the virtual laboratory continue: the elodea plant. Simple lab where students place elodea leaves in hypertonic solutions the solution will cause an observable change in the cells due to osmosis cytoplasmic streaming is also visible page includes photos of what students will observe. Plasmolysis - the shrinkage of cytoplasm resulting from loss of water by osmosis, in a cell placed in a hypertonic solution turgor pressure - in plant cells, the pressure on the cell wall that results because of the influx of water in osmosis lab diagram. Osmosis in plant cells plasmolysis of elodea purpose the purpose of this lab is to observe the effect of a hypertonic and hypotonic osmotic environment on a plant cell the process of cell shrinkage due to a hypertonic environment is knows as plasmolysis.
Diffusion and osmosis abstract in this diffusion and osmosis lab a total of three experiments were performed when the elodea cell was placed into the distilled water, the cell became swollen and underwent lysis however. Here we provide two versions of a proof-of-concept osmosis lab that can be done with the microscope elodea can be purchased at pet or aquarium stores and can be stored in an aquarium or beaker of water in the sunlight for several weeks. Using potatoes for osmosis and diffusion labs easy materials list easy set up and clean up involves calculations and graphing 5% sodium chloride solution, medicine droppers, elodea plant, 10% sodium chloride solution, distilled water, potatoes, various sugar solutions, 100 ml. Student 1 lab report dr newton 10/18/12 lab report plasmolysis in elodea leaves introduction the purpose of this lab was to induce what concentration of nacl causes plasmolysis in elodea.

Bsc 2010l - principles of biology 1 lab lab topic 3 diffusion and osmosis propose a question about the movement of water in elodea leaves bsc 2010l lab topic 3 author: mark chiappone subject. Labbench activity water potential because you will be working with potato cells in the laboratory, you need to understand the concept of water potential. Osmosis in plant cells plasmolysis of elodea the ability of water to pass through cell membranes is also called osmosis under different environmental the purpose of this lab is to observe the effect of a hypertonic and hypotonic osmotic environment on a plant cell. Osmosis the purpose of this lab is to assist you in learning about a type of diffusion that involves the movement of water you will examine how changes in concentration. Lab: osmosis in plant cells introduction: in order for a cell to maintain homeostasis and out of the live cells of the plant elodea as well as the cells of a red onion part 1: elodea elodea is a plant that lives in fresh water lakes and ponds.
