History of nucleoplasm Franz Bauer later characterized and depicted the nucleus, which includes the nucleoplasm, after the Dutch microscopist Leeuwenhoek initially noted its presence in 1682. However, it wasn’t until Robert Brown’s presentation to the Linnean Society in 1831…
History of Golgi Apparatus: Italian cytologist Camillo Golgi first observed the Golgi apparatus in 1897. Golgi developed the Golgi stain, commonly known as the reazione era, during his early research on nerve tissue. Using this method, silver nitrate is…
Ribosomes: Ribosomes ( singular= Ribosome) are present either in the cytoplasm or loosely attached to the cell membrane (plasma membrane) of the cell. they are complex structures that contain ribonucleic acid (RNA) which is known as ribosomal RNA (rRNA) and…
Introduction The nucleus, the central organelle within eukaryotic cells, is encapsulated by a vital structure known as the nuclear envelope. This double-membraned boundary plays a crucial role in maintaining the integrity of the genetic material and orchestrating various cellular processes.…
Introduction and history of the nucleus: The red blood cells of other vertebrates still have nuclei, in contrast to those of mammals. Robert Brown, a Scottish botanist, described the nucleus in greater detail in a discussion he gave to…
Principle Importance of filtration in microbiology history In the early days of microbiology, liquids were filtered through hollow, unglazed porcelain candles. The long, convoluted channels through the filter’s walls absorbed the germs. In the 1890s, as interest in viruses…
What is Plate count method? For obligate and anaerobic bacteria, the Plate count method is the most frequently utilized technique. This method uses repeated dilution and colony forming unit (CFU) counts to isolate microbial colonies. With this method, the…
What is colony Morphology? An essential ability for identifying bacterial growth in the microbiology lab is observing colony morphology. The visual qualities of a bacterial colony on an agar plate are known as a colony. Morphological features of a…
Who discovers the most probable number? Understanding and Teaching the Most Probable Number Technique, published in 1975 .J. L. Oblinger and J. A. Koburger 540-545 in J. Milk Food Technol., 38(9). Define Most Probable Number Using ten-fold dilutions of…
History Phase contrast microscopy is a contrast enhancing optical technique that can be used to create high-contrast images of transparent specimens like living cells (typically in culture), microorganisms, thin tissue slices, lithographic patterns, and fibers. It was first introduced…
