Question

what are hypotonic hypertonic and isotonic solutions

Answer 1

Hypotonic solution is that solution whose concentration of solute is lesser than the cell placed within it.
hypertonic solution is that solution whose concentration is greater than the cell placed within it.
isotonic solutions are those solution whose concentration is equal to the cell placed within it.

Answer 2

hhypotonic means if the medium surrounding the cell has a higher water concentration than the cell these solution is hypotonic .Isotonic mean if the medium exactly same water concentration aS tHe cell there will be no net moment of water across the cell membrane these sol. is iaotonic and .Hypertonic means if the medium has lower concentration of water than the cell meaning that is a very concentrated solutions the cell will lose water by osmosis these sol is hypertonic
