(a) A cell containing higher water concentration than the surrounding medium
(b) A cell having low water concentration then tha surrounding medium.
(c) A cell having equal water concentration to its surrounding medium.

Text Solution

Verified by Experts

High water concentration occurs in hypotonic solution, low wte concentration in hypertonic solution while equal water concentration in istonic solution.
(a) A cell having higher water content or hypotonic cell sap will undergo exosmosis and, therefore, lose water. It may undergo plasmolysis.
(b) A cell having low wate concentration or hypertonic cell sap will undergo endosomsis and absorb water from outside. It would become turgid.
(c ) A cell having isotonic cell sap will neither gain nor lose water to the external medium.
