English explorers and colonists named Hudson Bay after Sir Henry Hudson who explored the bay beginning August 2, 1610 on his ship Discovery. On his fourth voyage to North America, Hudson worked his way around Greenland's west coast and into the bay, mapping much of its eastern coast.
PLASMOLYSIS IN ELODEA CELLS. Osmosis is the diffusion of water across a membrane from an area of high water concentration to an area of low water concentration. This movement of water may be harmful to cells. A hypertonic solution can result in the plasmolysis of a cell when the water in a. living cell osmoses out of the cell and the cell becomes dehydrated. Most cells live in an isotonic solution where the movement of. water is constant into and out of the cell (equilibrium).
In this lesson, students will microscopically detect the presence of chloroplasts, cell walls, and cell membranes of the common aquarium plant, Elodea. Students will then determine the effects of different salt solutions on the Elodea plant cell structures. By adding salt water to the Elodea cell environment, students will observe the process of plasmolysis, shrinkage of the cell contents due to water loss. However, you should not focus on terminology, but rather what happens during plasmolysis.
