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).
Cells without walls will swell and may burst (lyse) if excess water is not removed from the cell. Cells with walls often benefit from the turgor pressure that develops in hypotonic environments. Cells in Hypertonic Solutions. Hypertonic comes from the Greek hyper, meaning over, and tonos, meaning stretching. In a hypertonic solution the total molar concentration of all dissolved solute particles is greater than that of another solution, or greater than the concentration in a cell. If concentrations of dissolved solutes are greater outside the cell, the concentration of water outside is correspondingly lower.
