Answer:True
Explanation:Solution can occur as three types which are isotonic , hyotonic and hypertonic depending on solute concentration
An isotonic solution occurs when the concentration of solute is balanced inside and outside the cell. A hypotonic solution is one in which concentration of solutes is more concentrated inside than outside the cell hence salt get concentrated inside the cell of the celerly stalks which make the walls weaker and it becomes lumpy.
Hypertonic solution is one which t
solutes is more concentrated outside than inside the cell hence in water concentration is on the outside cell of celery stalks which makes it hard and stiff.
