The metabolites which are required for the growth and maintenance of cellular function are called primary metabolites, while such metabolites which are not required for the growth and maintenance of the cellular functions and are the end products of the primary metabolism are called as secondary metabolites. Microbial Metabolic products are the low molecular weight compound, necessary for the cell's or body metabolism processes. These products are classified as the primary and secondary … [Read more...]

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...]

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...]

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...]

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...]

Yeast is a single cell organism, which is usually a thread and filamentous in shape, appear white or colourless and divide asexually. On the other hand's Molds are multicellular, appearing round or oval shape and appear in various colour, they divide sexually or asexually. There are 1500 types of yeast present; they are used in industry for the baking purpose, additive, in alcohol production, food beverages. Yeast is very common and can be found in fruits, vegetables, on the skin of mammals … [Read more...]

Prokaryotes are simple, small cells, whereas eukaryotic cells are complex,  large structured and are present in trillions which can be single celled or multicellular. Prokaryotic cells do not have a well-defined nucleus but DNA molecule is located in the cell, termed as nucleoid, whereas eukaryotic cells have a well-defined nucleus, where genetic material is stored. Based on the structure and functions, cells are broadly classified as Prokaryotic cell and Eukaryotic cell Prokaryotic Cells are … [Read more...]
