‘Not only do Prokaryotes have a wide range of metabolic activities crucial for maintaining the biosphere, they also exert significant impacts on human life’ discuss this statement fully using named examples. Prokaryotes are unicellular microorganisms without a nucleus; they are divided into two groups’ Eubacteria and Archaebacteria. These microorganisms are very small and invisible and are known as the most dominant species on the earth’s biosphere as they are found almost everywhere on earth, they are predominately, found in our body’s immune system, and they are mainly responsible for the decomposition of dead matter which in return benefits both plants and animals. They are found in the air that we breathe, in the food that we eat, in deep seas, in cold and hot temperatures, sea corals, in salt water, fertile soils and in short, they are so diverse in their form of habitation and adaptation, as different types of bacteria adapt to different types of environments in different forms of life. However, bacteria are grouped according to their uniqueness, features, structure, functions, and contribution to human life. Prokaryotes are so beneficial to us because they act as defences to protect us from various diseases. The essay will examine the significant impact of prokaryotes to human life.
The word bacteria may be frightening to most of us; in many cases it is often associated with many negative and harmful aspects such as infectious diseases, dental decay, mould and smell. But bacteria provide us with both positive and negative aspects which can contribute significantly to our human life.
Prokaryotes are very important to the biosphere, as a great deal of life depends on them directly or indirectly. They share different types of relationships with other forms of life including both plants and animals (eukaryotes) which are mainly depended on prokaryotes.
