The difference between gram positive vs gram negative bacteria is based on their staining color during the gram stain test. Using the gram staining technique, bacteria have been differentiated into gram-positive and gram-negative bacteria. The ability to differentiate bacterial cells is essential for various reasons. This host of reasons varies from diagnosing infection to checking … Read more
Not all organisms are multicellular, some organisms exist as just a single cell and are called a single-celled organism or a unicellular organism. Cells come together to form multicellular organisms like plants and animals and that is why we call cells, the building blocks of life. However, unicellular organisms are not like multicellular organisms that … Read more
The Gram staining procedure is a differential staining technique used to differentiate bacterial cells into gram-positive or gram-negative bacteria based on the differences in their cell wall components. At the end of the gram stain, gram negative bacteria stain pink/ red while gram positive bacteria stain purple or blue. Gram-negative bacteria are characterized by their … Read more
The most common gram-positive bacteria examples include Staphylococcus, Streptococcus, Bacillus, Clostridia, Listeria, and Corynebacterium. These gram-positive bacteria representative species are pathogenic and cause several diseases. All gram-positive bacterial cells are bounded by a single-unit lipid membrane. Generally, the cell walls of gram positive bacteria contain a 20-80 nm thick layer of peptidoglycan. This peptidoglycan is … Read more
Definition Euglena can be defined as a known genus consisting of species of unicellular flagellates that exhibit both plant and animal characteristics. Even though, euglena share some characteristics of both plants and animals, they are not seen as plants or animals but as protists. They may be plant-like in that they can manufacture their own … Read more
The gram stain procedure is a process that involves different steps, methods, or techniques. Gram staining results are used to differentiate bacteria as gram-positive or gram-negative. In microbiology, the gram stain procedure is one of the most crucial staining techniques. This gram staining technique helps in the diagnosis of a disease or a pathologic condition. … Read more
Nevertheless, the cell wall of bacteria is not like that of plants and other organisms due to the presence of peptidoglycan (also known as murein) which is located immediately outside the cell membrane. The bacteria cell wall is made up of peptidoglycan which makes the cell wall rigid and determines the cell shape. The structure … Read more
What is a Protist? A protist is a member of the kingdom Protista which includes all eukaryotic organisms that are not plants, animals, or fungi. Protists are simple unicellular eukaryotic organisms though some can be found as a colony of cells or in multicellular form. The majority of protists inhabit the aquatic and damp terrestrial … Read more
