Question

A(n) _______ solution has the same concentration of water as the cell placed in the solution.

Answer 1

An Isotonic solution has the same concentration of water as the cell placed in the solution.

What is tonicity?

• Tonicity may be a measure of the effective osmotic pressure gradient; the water potential of two solutions separated by a partially permeable cell membrane.
• Tonicity depends on the relative concentration of selective membrane impermeable solutes across a cell wall which determine the direction and extent of osmotic flux.

What is Isotonic solution?

• A solution is isotonic when its effective osmole concentration is the same as that of another solution.

• In biology, the solutions on either side of a cell wall are isotonic if the concentration of solutes outside the cell is equal to the concentration of solutes inside the cell.
• In this case the cell neither swells nor shrinks because there is no concentration gradient to induce the diffusion of large amounts of water across the cell membrane.
• Water molecules freely diffuse through the cell wall in both directions, and because the rate of water diffusion is the same in each direction, the cell will neither gain nor lose water.
