• Chemical composition of cell. • As we know that all living bodies are made up of cells and cell contains living matter called protoplasm. • Actually chemical composition of protoplasm still not known perfectly. • How ever chemically it contains 70 to 90% water and other molecules. • The organic molecules contain elements such as carbon, hydrogen, nitrogen, oxygen, phosphorus and sulphure. • They make up about 90% of biochemical which ultimately make up

CHEMICAL COMPOSITION OF CELL § § Following are the some properties and function of these elements. ELEMENT. Carbon ATOMIC MOLECUL NO/ AR FROM. WEIGHT. 6/12 Co 2 FUNECTION. Basic elements of organic compounds fix during photosynthesis. Hydrogen 1/1 H 2 O It is a raw material of plants in photosynthesis. Oxygen 8/16 O 2 Use in aerobic respiration. NO 3 -NH 4 Use formation of amino acids and protenis, nucleic acid, harmones, coenzymes. Phosphorou 15/30 s H 2 PO 4 HPO 4 Component of nucleic acids, ATP, phospholipids, co-enzyme etc. Sulphur SO 4, H 2 SO 4 Components of proteins and enzymes. Nitrogen 7/14 16/32
