Osmosis

Worksheet 12 Osmosis and Hypotonic, Hypertonic, and Isotonic Solutions

QuestionAnswer
Define osmosis diffusion of water
Define hypotonic solution a lower concentration in the solution, making the cell swell
Define hypertonic solution a higher concentration in the solution, making the cell shrivel
Define isotonic solution equal on both sides of the membrane
When a cell is in a hypotonic solution, how will water molecules move? The water rushes into the cell and lowers the concentration in the cell.
When a cell is in a hypertonic solution, how will water molecules move? goes out so concentration will rise
When a cell is in an isotonic solution, how will water molecules move? move equally in and out
Explain how hypotonic and hypertonic solutions can make a plant rigid and firm or make it wilt. Hypotonic makes it swell=rigid and firm, hypertonic does the opposite and makes it wilt
Osmosis is a form of passive transport. Explain how facilitated diffusion, which is another form of passive transport, is different from osmosis. no energy is used, but a protein facilitates, or helps, the transport to occur
