What are the 3 states of tonicity for cells in a solution?
Three terms—hyerptonic, hypotonic, and isotonic—are used to describe whether a solution will cause water to move into or out of a cell: If a cell is placed in a hypertonic solution, there will be a net flow of water out of the cell, and the cell will lose volume.
What is hypertonic hypotonic and isotonic solution?
In comparing two solutions of unequal solute concentration, the solution with the higher solute concentration is hypertonic, and the solution with the lower solute concentration is hypotonic. Solutions of equal solute concentration are isotonic.
What is osmosis Khan Academy?
Osmosis of water from an area of lower to an area of higher solute concentration across a semipermeable membrane.
What is the tonicity of the solution?
In biology, the tonicity of a solution usually refers to its solute concentration relative to that of another solution on the opposite side of a cell membrane; a solution outside of a cell is called hypertonic if it has a greater concentration of solutes than the cytosol inside the cell.
What is a correct example of tonicity?
Which is a correct example of tonicity? -Water is hypertonic to red blood cells. -Turgor pressure is created when a plant cell swells in a hypotonic solution.
What is tonicity of a solution?
“Tonicity is the ability of a solution to affect the fluid volume and pressure in a cell. If a solute cannot pass through a plasma membrane, but remains more concentrated on one side of the membrane than on the other, it causes osmosis.”
What is tonicity biology?
Tonicity is defined as the ability of a solution surrounding a cell to cause that cell to gain or lose water (Urry et al., 2017). While osmolarity is an absolute quantity, tonicity is relative. If two solutions have the same concentration of nonpenetrating solutes, they are considered isotonic.
