Anatomy and Physiology of Animals/The Cell The movement of water across a selectively permeable membrane from a region where water is highly concentrated to a region where its concentration is lower is known as osmosis. Osmosis is a special kind of diffusion, the diffusion of water.

Selectively Permeable Membranes: Definition & Examples All cells are enclosed with a cell membrane. A selectively permeable cell membrane is one that allows certain molecules or ions to pass through it by means of active or passive transport. Active transport processes require the cell to expend energy to move the materials, while passive transport can be done without using cellular energy.

Bright Hub Education Now hypotonic, hypertonic, and isotonic solutions usually deal with cellular osmosis which diffuses over a selectively permeable membrane. Osmosis is the movement of water and tends to diffuse by moving the water from areas of higher concentrations to areas of lower concentrations.ypertonic Solutions. Hypertonic solutions are different from isotonic solutions in that cells often lose water. Cells have a water concentration that is greater inside the cell rather than outside of the cell. Furthermore, the solutes outside of the cell are greater than the solutes inside of the cell.

- An isotonic solution refers to the state when two solutions have equal concentration of solutes across a semipermeable membrane. This state allows for the free movement of water without the dilution of solutes on either side and keeps cells functioning properly. To unlock this lesson you must be a Study.com Member.

- Hypertonic. Definition. adjective. Having a greater degree of tone or tension. Having a higher osmotic pressure in a fluid relative to another fluid. Of or pertaining to a solution (e.g. extracelllular fluid) with higher solute concentration compared with another. (see: hypotonic, isotonic). For example, if the extracellular fluid has greater amounts of solutes than the cytoplasm, the extracellular fluid is said to be hypertonic. Supplement. A cell placed in a highly concentrated solution will result in the water molecules diffusing out of the cell.

- isotonic. 1. denoting a solution in which body cells can be bathed without net flow of water across the semipermeable cell membrane. 2. denoting a solution having the same tonicity as another solution with which it is compared. 3. maintaining uniform tonus.

- isotonic-- having an equal concentration of solute isosmotic-- having the same osmotic pressure Osmotic pressure is the pressure created by an unequal concentration of solutions on either side of the SPM (semi-permeable membrane). The concentration of solute is, obviously, the concentration of solute on either side of the SPM.

isotonic Of a fluid that exerts the same OSMOTIC PRESSURE as another, especially as that of the body fluids. Body cells, such as red blood cells, can be immersed in an isotonic solution without being caused to change shape. ‘Normal’ saline is isotonic with blood.

- If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, the relative concentrations of solute and water are equal on both sides of the membrane. There is no net water movement, so there is no change in the size of the cell.

Isotonic vs hypotonic vs hypertonic- page 2 tonicity is the relative osmolality of a solution. a solution is isotonic if its tonicity falls within (or near) the normal range for blood serum - from 275 to 295 mosm/kg. a hypotonic solution has lower osmolarity (<250), and a hypertonic solution has higher osmolarity (>350).

Bright Hub Education As a result, nothing happens because the concentration of water solutes outside of the cell are equal to the solutes within the cell. In the same respect, the water concentration on both sides is also equivalent. Isotonic solutions are commonly used in medical situations.For example, hospitals use isotonic saline solutions for IVs for patients. If you clean contact lenses, you use a isotonic saline solution to clean the protein from your lenses.ypertonic Solutions. Hypertonic solutions are different from isotonic solutions in that cells often lose water. Cells have a water concentration that is greater inside the cell rather than outside of the cell. Furthermore, the solutes outside of the cell are greater than the solutes inside of the cell.

- The cell membrane is a severely permeable membrane, and therefore it regulates. the passage of substances into and out of the cell. Osmosis: The diffusion of water (or some other solvent) across a selective permeable. membrane; water diffuses to a hypertonic area. When water enters or leaves the cell it. is usually accomplished by osmosis.

What is Isotonic solution? in Biology.? In general biology terms, an isotonic cellular milieu occurs when an equal solute concentration exists inside and outside the cell. In practical clinical terms, an isotonic solution has the same overall concentration of solutes as the usual aqueous (watery) part of blood. 0.9% w/v of NaCl .

Define hypotonic, hypertonic, and isotonic.? Hypertonic Definition. HYPERTONIC solution: has higher concentration of solute than the cell, water diffuses out and the cell shrivels HYPOTONIC solution: has a lower concentration of solute than the cell causing water to diffuse into the cell. The cell will swell and could burst. ISOTONIC solution: has the same concentration of solute as the cell so water diffuses in and out evenly
