WebIf the plant cells become hypertonic, as occurs in drought or if a plant is not watered adequately, water will leave the cell. Plants lose turgor pressure in this condition and wilt. Figure 3.23 The turgor pressure within a plant cell depends on the tonicity of the solution that it is bathed in. (credit: modification of work by Mariana Ruiz ... 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.

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). WebTo observe the effects of tonicity on plant cells, prepare a wet mount of an Elodea leaf (or similar freshwater plant). For the initial preparation, use pond water or water from the tank … WebTonicity describes how the extracellular concentration of solutes can change the volume of a cell by affecting osmosis, often correlating with the osmolarity of the solution, (i.e., the total solute concentration of the solution). linear model drawing

"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. " - Plant tonicity

WebTonicity is defined as the ability of a solution which surrounds the cell to cause the cell to gain or lose water. It depends on the relative concentration of solutes across a cell membrane which determines the direction and extent of osmotic flux. Three terms are used to determine tonicity- hypertonic, hypotonic, isotonic.
