is an isotonic plant cell the same as a turgid plant cell?

Question

are they the same, where the cell is full of water?... please include diagrams if u can thanks

Answer 1

Isotonicity has nothing to do with turgidity. A cell in isotonic status simply means that the ionic concentration of solutions both inside and outside the cell are equal. In an isotonic situation there is no net movement of water from one side of the cell membrane to the other.
A turgid plant cell could be in an isotonic situation but probably not. A turgid cell, is at maximum capacity for the cell volume. Usually a turgid cell has a very large vacuole that is responsible for that condition. The volume of fluid in that vacuole is regulated by the metabolism of that cell. These cells usually play a regulatory role for the plant. Cell turgidity is utilized to regulate guard-cell conditions around a leaf stoma. Turgidity also plays a part in plant verticality (uprightness) vs. wilt/droop.
