The living organisms are classified into different groups by means of their differences and similarities. Two of the major/ most important groups are the prokaryotes (Bacteria and Archaea) and eukaryotes (from plants, animals till malaria parasites and fungi). The difference between them is that eukaryotic cells contain membrane-bound organelles, such as the nucleus, whereas the prokaryotic cells don’t. There is also a difference in their cellular structure due to the lack of chloroplast, cell wall and mitochondria in the prokaryotic cells. Furthermore, the DNA material comes in different forms, the DNA of eukaryotic cells comes in forms of chromosomes while the DNA of the prokaryotic cells comes in forms of plasmids (a circular and double-stranded
3. Introduction Microorganisms are microscopic organisms that can be found all around us. They cannot be seen with a naked eye, but can be viewed with the use of a microscope. Microorganisms occupy a wide range of environments. They can be harmful or beneficial.
Eukaryotes are generally in the protista, plantae, fungi, and animalia kingdoms. Prokaryotes are in the eubacteria and archaebacteria kingdoms, which previously formed one kingdom called monera. Eukaryotes are generally in multicellular kingdoms, while prokaryotes are in microscopic and unicellular organisms. Habitats also determine the survivability of the cells. Prokaryotes live in strange environments where eukaryotes can’t survive.
Thus, the bacteria can use virtually any organic structure. [1][2] Bacteria as pathogens Although they are the smallest cells in biocoenosis, their role is even more important. Some bacteria are even able to assimilate (e.g. cyanobacteria or "blue-green algae"). Some of the bacteria decays or rots other organisms to feed themselves.
Biomes are different to ecosystems because a biome is an area of land that is classified depending on the animals that live in it. Biomes are what keep animals alive by offering food, water, light and soil. Biomes aren’t always in the same place. Because of climate change forests die and dry out. An ecosystem is an area of land that has animals, plants insects and other living things.
Dr Tracy Ainsworth stated “it is very likely that these microorganisms play a vital role in the capacity of coral to recovering from bouts of bleaching caused by rising temperatures.” Corals rely on these good bacteria’s crucially although we don’t yet understand these microbe’s ell enough to know how they influence coral survival, which is vital in maintaining the food web of the Great Barrier Reef. These good bacteria as well as other decomposers break down dead organics material and turn nutrients to the sediment. This energy is then obtained by the producers and the cycle begins
Another microbial life are protist. They are unicellular eukaryotes. Types of protist includes protozoans and slime molds. Fungi, is also an example of microbial life. They are unicellular or multicellular eukaryotes and are made up of a mass of threadlike hyphae forming mycelium.
Microorganisms are tiny organisms that have been present on life from the past few billions of years. These tiny organisms are vital for the existence of human mankind and exist everywhere, in and out of the human body. Microbes include bacteria, fungi, protists, viruses and archae (1). Microbes however have indispensible advantages and benefits in many different areas. One example includes the industry of food production, where microbes hold a immense responsibility both on small scale, inside homes and on big scale too.
But this classification system proved to be inadequate as there were many organisms that did not fall into any of the categories. Afterwards, the classification system for living organisms has undergone several changes. However, the place of plant and animal kingdoms remains consistent under all different systems. Systematics / Taxonomy Systematics is the study of identification, nomenclature,
Introduction Biodiversity is the unevenness amongst the species from all sources, including aquatic and terrestrial ecosystems and the ecological complexes of which they are a part. It is essential for stabilization of ecosystem, protection of overall environmental quality for understanding intrinsic worth of all species on the earth. It is the variety of life forms at every level viz. molecular, population, species and ecosystem of natural organization. United Nations Earth Summit (1992) defined biodiversity as, the variability among living organisms from all sources viz.
