Answer:
What is Tonicity?
Tonicity is a measure of the effective osmotic pressure gradient; the water potential of two solutions separated by a semipermeable cell membrane. In other words, tonicity is the relative concentration of solutes dissolved in solution which determine the direction and extent of diffusion. It is commonly used when describing the response of cells immersed in an external solution.
Explain briefly of Isotonic, Hypotonic and Hypertonic.
Isotonic is a term used to describe solutions and chemistry and, sometimes, muscles in human biology. In chemistry, a solution is said to be isotonic when it has the same concentration of solutes as another solution across a semipermeable membrane.
Hypotonic is a descriptive word relating to hypotonicity. In cellular level, hypotonicity may pertain to a property of a solution with a comparatively lower concentration of solutes relative to the amount of solutes in another solution. Also, a solution is described as hypotonic when the other solution being compared with has less osmotic pressure in a fluid compared to another fluid.
Hypertonic Hypertonic refers to a solution with higher osmotic pressure than another solution. In other words, a hypertonic solution is one in which there is a greater concentration or number of solute particles outside a membrane than there are inside it.
