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).
When a cellâs cytoplasm is bathed in a hypotonic solution the water will be drawn out of the solution and into the cell by osmosis. If water molecules continue to diffuse into the cell, it will cause the cell to swell, up to the point that cytolysis (rupture) may occur. The opposite of a hypertonic environment is a hypotonic one, where the net movement of water is into the cell. If the cell contains more impermeable solute than its surroundings, water will enter it. HOW IT AFFECTS ANIMAL CELLS; In an animal cell, hypotonic solutions cause them to swell, they become bloated and triple their original size.
