Question

What 3 factors are responsible for the success of the bacteria? 1. 2. 3. List 3 reason why it is important to classify bacteria. 1. 2. 3.

Answer 1

Answer of first part of Question No. 1

1. Adaptation : bacteria easily adapt with the external enviourment as the other species of the earth do. Bacteria adapt very rapidly due to very short life cycle which is described in second factor. Bacteria can adapt their nutritional socurces also. Adaptility is main factor on which evolution depends. Adaptation result in survival of the bacteria in changing enviourment. Even bacteria adapts himself for surviving in the presence of an antibiotic. Which is known as bacterial Resistance. As the bacterial resistance develops bacteria survival increases.

2. Rapid Division: Adapting a new enviourment is a slow process. And evolve in subsequent divisions. In other species adapting may take hundreds/thousands of years. It depends on how many new progeny generated in a period. Bacteria may could devide so many times in a night that the species in the morning would be fully adapted with new enviourment. So the rapid division help in development of resistance against antibiotics.

3. Conjugation : conjugation is bacterial sexual process in which bacteria transfer copy of its genetic material to another bacteria. Suppose one bacterial got antibacterial resistance. This genetic information of resistance can be transferred to another. Then these 2 can transfer this genome to another two. Then these 4 to another 4 and so on. If "n" time genetic information is transfered than "2 to the power n" new species will carry this genetic material .

So above theae 3 factors are responsible for suceas of bacteria.

Answer of second part of Question No. 2

follwing may be the reasons to classify bacteria

1. to identify a bacterial species:  bacteria are classified according to there shape, staining properties for identificatio of a specific bacteria. Such as cocci(round), bacilli(rod shape). Then arrangment of colony.

2. to Develop antibiotics. Bacterial of same basic properties can be targated by a single drug. Thia is due to same metabolic process. For example a single drug can work on all gram positive bacteria or all gram negative bacteria.

3. to develop culture medium: classification of bacteria in aerobic and anarobic hints us about its survival enviourment. All aerobic bacteria can be cultured in same medium. And all anaerobic in a singlw medium.
