Book Description
The word 'Cell' is omnipresent in different aspects of human life and invariably used everyday, But in its entire variable form word 'Cell' has the same meaning i.e. close compartment. So, in biology, cell is defined as the basic structural and functional unit of life. Life exist in different variable forms but they all possesses one thing common which is said to be 'Unity in diversity' i.e. Cell. The concept of life cannot be imagined without the presence of cell, the closed compartment within the boundary of which all the essential life processes, nutrition, digestion, excretion, respiration, reproduction, etc. takes place in an organized manner. All these essential life processes occurs thorough thousands of complex biochemical reactions, irrespective of size, shape and different biological form, whether it is prokaryotic cell or eukaryotic cell, whether it is a cell of simple unicellular organism or of multicellular organism, fundamentals of life processes are similar. In this respect cell is said to be 'Biochemical Factory'. Although fundamentals of life processes are similar still the nature of biochemical reactions in a cell of different biological forms are different, as the information for carrying out biochemical reactions are different. This information which is in the coded form of DNA is responsible for different structural and functional features of different life forms. Thus, DNA acts as a 'Constitution' which bears predefined model code of conduct, is the most important prerequisite for the very existence of life. Hence, the cell is just like any other 'organization' whose functions are performed according to predetermined code of conduct, where all the cell organelles acts in perfect co-ordination with each other for actualization of coded information in DNA. This peculiar functioning of biological forms leads to origin of term 'Organism' whether it is bacteria or highly evolved mammal.
