Despite being in the same category of prokaryotes, archaea and bacteria show variances in their genetic makeup, as the metabolic pathways, and other enzymes, genes possessed by the archaea closely resembles eukaryotes rather bacteria. Simple, microscopic, ambiguous microorganisms mark their presence universally, whether its deep in water, high temperature, soil or any extreme conditions. The evolving history of these cells is considered to be old as more than 3.5 billion years ago. Archaea … [Read more...]
Difference Between Staphylococcus and Streptococcus
Staphylococcus is the group of Gram-positive bacteria that divides in variable directions (multiple axes) and forms the assembly or clusters (grape like). They are round shape and responsible for causing the multitude of diseases. On the counterpart Streptococcus are also Gram-positive bacteria, present in respiratory tract and mouth. They are responsible for causing rheumatic fever, impetigo, scarlet fever, tonsillitis, while some other species though commonly found in the throat but does not … [Read more...]
Difference Between Primary Metabolites and Secondary Metabolites
Metabolism involves a whole set of biochemical reactions constantly occurring inside a living body to keep it alive and active. The metabolites are the intermediate compounds or end products generated as a result of these metabolic transformations. We can categorise the metabolites in two parts based on their origin and function- Primary and Secondary metabolites. The primary metabolites directly influence the vital process like growth, development and reproduction of any organism. In … [Read more...]
Difference Between Gram Positive and Gram Negative Bacteria
The gram-positive bacteria retain the crystal violet and stain purple, while the Gram-negative bacteria lose the crystal violet and stain red from the safranin counterstain. So by Gram-staining technique and the color they retain is crystal violet or not describes the features of the bacteria, as well they are characterized as positive or negative. The word 'gram-staining' technique arose from the Danish bacteriologist Christian Gram in 1884. This stain is a weak alkaline solution of a … [Read more...]
Difference Between Aerobic and Anaerobic Respiration
Aerobic denotes the term 'in the presence of oxygen' while the word anaerobic denotes the 'absence of oxygen'. So the respiration which occurs in the presence of oxygen is called as aerobic respiration, on the other hand, respiration occurring in the absence of oxygen is known anaerobic respiration. So accordingly the chemical reaction involving the breakdown of the nutrient molecule with the aim of producing energy is called respiration. Thus the energy required by the body to perform well … [Read more...]
Difference Between Infection and Disease
Infection serves the closest way through which the microorganisms can cause disease and gradually when this infection starts weakening the immune system, and harm the body for a long or short term is called disease. In general, people get confused with these words and use interchangeably. But these terms are totally different in their meaning and applicability, though they share the same passage and reasons of occurrence. Disease depends on the kind and place of occurrence of infection in the … [Read more...]
Difference Between Monera and Protista
Monera is a unicellular organism, they have a prokaryotic cellular organization, which means they lack well-defined, membrane-bounded organelles and nucleus. On the other hand, Protista is also unicellular organisms, but consist of eukaryotic cellular organization and well defined,membrane-bounded organelles and nucleus, this is the main difference between them. All forms of life on earth are divided into five categories on the support of the nutrition and energy they obtain, kind of cell … [Read more...]
Difference Between Yeast and Mould
Both yeast and mould belong to kingdom fungi. But still, they exhibit many differences, including their appearance, habitat, method of reproduction, growth conditions etc. At present, there are around 1500 types of yeast, whereas 400,000 species of moulds are found on earth. On the one hand, the yeasts are unicellular microorganisms with a round or oval-shaped, colourless appearance. Contrastingly the moulds are filamentous, thread-like, multi-coloured fungi. The growth conditions also … [Read more...]
Difference Between Prokaryotic Cells and Eukaryotic Cells
Prokaryotic cells are the smallest living entities on the planet. They are small, simple cells with uncomplicated living mechanisms. This simplicity is due to the absence of multiple organelles with complex structures and more complex mechanisms of action. On the other hand, the eukaryotic cells have a larger framework and an intricate mechanism of living. This complexity is due to the presence of well defined, membrane-bound cellular organelles. The prokaryotes are lower organisms that are … [Read more...]
