WebThe tonicity of a solution determines if a cell gains or loses water in that solution. The tonicity depends on the permeability of the cell membrane for different solutes and the concentration of nonpenetrating solutes in the solution within and outside of the cell. WebPlant cells function best in hypotonic solutions whereas animal cells function best in isotonic solutions. The main factors that affect the rate of osmosis are water potential gradient, surface area, temperature and the presence of aquaporins. The water potential of plant cells, such as potato cells can be calculated using a calibration curve.

WebJun 8, 2024 · Tonicity describes how an extracellular solution can change the volume of a cell by affecting osmosis. A solution’s tonicity often directly correlates with the … WebTonicity is a property of a solution in reference to a particular membrane, and is equal to the sum of the concentrations of the solutes which have the capacity to exert an osmotic force across that membrane. Tonicity, also, depends on solute permeability (permeant solutes do not affect tonicity; impermeant solutes do affect tonicity). WebTonicity is a concern for all living things, particularly those that lack rigid cell walls and live in hyper- or hypotonic environments. For example, paramecia—pictured below—and amoebas, which are protists that lack cell walls, may have specialized structures called … Learn for free about math, art, computer programming, economics, physics, chem… Lesson 7: Mechanisms of transport: tonicity and osmoregulation.
