Although they are not very complex morphologically, the tiny bacteria nevertheless have highly complex physiological, biochemical, cytological, and genetical characteristics making them a valuable tool for understanding the various intricacies of life
Due to their extreme simplicity in structure, small size favouring rapid cell division, highly resistant nature and diversified mode of nutrition, bacteria are of universal occurrence. They are present in our mouth and flourish in intestine. They are present in air we breathe and in food we eat; they abundantly occur in fresh and salt water, soil water and even in ice. Their most favourable habitat is soil, where they occur in abundance mainly in the upper half feet. In a handful of garden soil, the bacterial population may outnumber the human population on the earth.
They live in all conditions not fatal to living beings and are among the most numerous of all living beings present in almost every conceivable environment. Some bacteria are deadly parasites of plants, animals and human beings; some live as mutualists with plants or as commensals in the alimentary canals of animals. Some bacteria may remain viable when cooled upto -190°C, while others may remain viable when boiled upto 78°C.	Your Ad Here
