Question

what are hypotonic,hypertonic and isotonic solutions?

Answer 1

Hypotonic = the solution has a lower solute concentration than the cell so water moves into the cell causing plant cells to swell and animal cells to swell and burst Hypersonic = the solution has a higher solute concentration than the cell so water moves out of the cell and into the solution causing the cell to plasmolyze Isotonic =he concentration of solutes is equal inside and outside the cell so water moves across the membrane in both directions maintaining cell siz

Answer 2

A solution consists of two substances-
1.Solvent=that is present in excess (usually water)
 2. Solute= that is in small amount
1)HYPERTONIC SOLUTION- If a solution  has more amount of solutes than the cell, meaning that the cell is concentrated ( that has more amount of solute ) the cell loses water and shrinks, the solution is known as Hypertonic solution and the process is called Exosmosis.
2) HYPOTONIC SOLUTION- If a solution has more amount of solvent than the cell, meaning that the cell is dilute ( less amount of solute ) the cell gains water, the solution is known as Hypotonic solutuion and The process is called Endosmosis.
3) ISOTONIC SOLUTION- If the solution has similar (never write same or equal because not all the sol. have equal amount of solute and solvent) concentration of solute and solvent, there will be no net movement means the size of cell will remain same and hence the solution is called as Isotonic solution.( Process- no net movement)
