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).
Hypotonic-Means the solution with a low solute concentration, so when a cell is placed in a hypotonic solution, it takes up water and swells and may burst. Isotonic-Means having the same concentration of solutes so it will not affect a cell.Effect of osmosis in plant cells.Plant cells are enclosed by a rigid cell wall. When the plant cell is placed in a hypotonic solution, it takes up water by osmosis and starts to swell, but the cell wall prevents it from bursting.The plant cell is said to have become turgid i.e. swollen and hard.nimal cells do not have cell walls. In hypotonic solutions, animal cells swell up and explode as they cannot become turgid because there is no cell wall to prevent the cell from bursting. When the cell is in danger of bursting, organelles called contractile vacuoles will pump water out of the cell to prevent this.
