CELL

All living organism are made up of cell. Cells are the structural,and functional unit of life. In unicellular organism single cell can perform all the life activities like respiration, reproduction, excretion, digestion etc and the structure of the organism is represented by single cell. But in case of multi cellular organism. The combined action of all the cell results the various life activities. So cell is known as the structural and functional unit of life.
DISCOVERY OF CELL:
The term cell was first of all introduction by pobert hook. He cut thin slice of work and examined it under his microscope. He found honey comb like structure and for each compartment,he gave the name cell. Anton von leeuwenhook observed the green bodies in plants called chloroplast. He also obserbed unicellular organisms like bacteria, sperm etc. Rudolf virchow stated that cells arise from pre-existing cells. German biologist Mathian-as-jocab scheiden and Theron Schwinn found that both plants and animals are made up cell.They proposed the famous cell theory; Also known as cell principle or cell doctrine.

• All living organisms are made up of cell.
• Cells are the structural and functional unit of life.
• All cells are fundamentally in similar chemical positions and metabolic activities.
• Cell arise from pre-exciting cells.
• In unicellular organism single cell , all the activities and in case of multiple cellular organism combined action of cells result the life activities.
• Cells are passed from one generation to other in form of living unit called generate.
• A cells most composed of well defined nucleus, nuclear membranes, cytoplasm, cell membranes, protoplasm, mitochondria etc.
