A fully stretched cell wall is exerting a restraining inward force called wall pressure on cell contents. This wall pressure is balanced by an equal but oppositely directed-force called turgor pressure in the cell contents, and when the cell wall can stretch no further, the cell is said to be fully turgid. Hence, when the cell is fully turgid its,
Wall Pressure (WP) = Turgor Pressure (TP).
Living. cells placed in isotonic solution (0.9% saline) retain their size and shape. This is based on the concept of
