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).
A plant or animal cell when kept in isotonic solution, no change is seen in their shape. The cells swell up in hypotonic solution due to endosmosis and may burst as seen in case of an animal cell.However, the protoplast shrinks away from the cell wall in plant cell (plasmolysis) when kept in hypotonic solution.Similarly the shrinkage of an animal cell is called crenation.TYPES OF SOLUTIONS Isotonic If the osmotic pressure of a solution in which a cell is placed is equal to its cell sap, it is isotonic solution. For example, parasites in our body as Plasmodium in RBC.imilarly the shrinkage of an animal cell is called crenation.
