Plasma membrane is an elastic living membrane made up of lipids and proteins, where as cell wall is a rigid non-living covering made up of cellulose. Plasma membrane acts as semipermeable membrane which allows only selective substances to pass through it. Cell wall provides rigidity and protection to cell. It is permeable.
Cell is the functional unit of life. It is defined as a tiny mass of protoplasm covered by plasma membrane which is capable of performing all functions of life.

High water concentration occurs in hypotonic solution, low water concentration in hypertonic solution while equal water concentration in isotonic solution. (a) A cell having higher water content or hypotonic cell sap will undergo exosmosis and, therefore, lose water. It may undergo plasmolysis. (b)Read more
High water concentration occurs in hypotonic solution, low water concentration in hypertonic solution while equal water concentration in isotonic 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 water concentration or hypertonic cell sap will undergo endosmosis 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.
Chromatin is intertwined mass of fine thread-like structures made of DNA and protein. During cell division (mitosis or meiosis), chromatin condenses to form thicker rod-like structures called chromosomes. Each chromosome consists of two similar halves called chromatids. Formation of chromosomes haviRead more
Chromatin is intertwined mass of fine thread-like structures made of DNA and protein. During cell division (mitosis or meiosis), chromatin condenses to form thicker rod-like structures called chromosomes. Each chromosome consists of two similar halves called chromatids. Formation of chromosomes having two similar halves or chromatids is meant for equitable distribution of chromatin which is hereditary material.
