Definition of Pseudostratified columnar epithelium A pseudostratified columnar epithelium an epithelium made up of only one layer of cells which creates the appearance of multiple layers due to the nuclei in the cells are located at various levels. It is histologically an epithelium that is simple, even though when viewed from a cross-section it could … Read more
Overview of Plant Cells Animals, fungi and protists are composed of at least one eukaryotic cell. However archaea and bacteria are composed of only one prokaryotic cell. Plant cells differ from cells belonging to other organisms due to their cell walls, chloroplasts and the central vacuole. Chloroplasts are organelles which are vital to the functioning … Read more
Principles Of Biotechnology Biotechnology has grown and changed a lot over the years. The old way of doing it was to use microbes to make products that people could use. Now, the new way is to use genes to make vaccines. So, the European Federation of Biotechnology (EFB) has come up with a new definition … Read more
Micropropagation Definition Micropropagation is a technique that is used to aid in propagating or cloning a particular genotype in the laboratory. It is generally accepted that there exist many ways that organisms are able to create similar copies of themselves. An excellent example is binary fission, which allows bacteria to divide, and then give birth … Read more
Biosafety Definition Biosafety defines as the application of safety precautions which reduces a laboratorians risk of exposure to potentially infectious material and limits contamination of the work environment and ultimately the community. Why we need Biosafety? We need biosafety because of; Different Biosafety Level Biosafety Level is also known as pathogen/protection level, it is referred … Read more
Biosafety guidelines provide guidelines, policies, and procedures that must be observed by all personnel who work in facilities handling microbiological agents, such as bacteria, viruses and parasites, fungi and prions. These guidelines are required for all institutions, including clinical and microbiological labs, biomedical research laboratories, teaching and training laboratories, and other healthcare institutions (e.g. hospitals, … Read more
What is Biosafety Cabinet? A biosafety cabinet (BSC), also known as a biological safety cabinet or microbiological safety cabinet, is a specialized laboratory workspace designed to handle materials contaminated with or potentially contaminated with pathogens requiring a specific biosafety level. The primary purpose of a biosafety cabinet is to provide a safe working environment for … Read more
Definition of Simple columnar epithelium The simple columnar epithelium, which is one type of epithelium, is made up of a single layer consisting of long, elongated cells. These cells are located in areas where absorption or secretion are the primary functions. The cells of the columnar epithelium can also be modified, just like cuboidal epithelium. … Read more
Definition of p-value The p-value, or estimated probability represents the most reliable probability of providing the lowest amount of significance, that the null hypothesis isn’t the case. Formula of p-value How to find p-value? P-values can be determined through comparing test results against the table of p-values for various scores. The scores calculated by the … Read more
What is Stratified cuboidal epithelium? Definition of Stratified cuboidal epithelium Stratified cuboidal epithelium is a type of epithelial tissue characterized by multiple layers of cells, with the surface layer consisting of cube-shaped cells. It is primarily found in glandular structures and plays roles in protection, selective absorption, and secretion. Stratified cuboidal epithelium labeled Stratified cuboidal … Read more
