Question

What are hypotonic, hypertonic and isotonic cells called???? What does turgid stand for??

Answer 1

Hypotonic solution means that the amount of solute is less than the amount of solvent in the solution. It is diluted solution.
Hypertonic solution is the opposite of hypotonic i.e. more solute less solvent. It is a concentrated solution. In isotonic solution, amount of solute equals amount of solvent.
When cells are in hypotonic condition, animal cells shrink and plant cells get flaccid. In hypertonic condition, animal cells rupture due to movement of more solute into the cells and plant cells get turgid. They do not rupture because of the rigid cell wall present outside. Animal and plant cells remain stable at isotonic conditions.
