Jamar Williams 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, in microbiology unicellular organisms are …
The contractile vacuole function in a cell is the structure for the regulation of water levels. This organelle is found mostly in single-celled organisms that lack a cell wall. Basically, the function of the contractile vacuole is to expand and contract in order to regulate the water levels in and outside the …
The central vacuole function and structure in plant cells are distinct from other cell types. Plant cells differ from other living cells because they contain chloroplast and can manufacture their own food. This kind of cell has a large central vacuole and a cell wall that plays a role in the structural …
A vacuole is a membrane-bound organelle found in the cells of plants, fungi, animals, and some protists. However, the prominence of vacuoles is greater in the cells of plants, fungi, and certain protists than in the cells of animals. A vacuole can be defined in biology as a space within a cell …
The Gram staining procedure in microbiology 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 …
The most common gram-positive bacteria examples in microbiology 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 …
Definition In Microbiology 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 …
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 …
