Stroma in chloroplast and Stroma in Animal Tissue
Stroma, as a term in botany, refers to the transparent fluid that surrounds the grana inside the chloroplast. In the stroma, there are the grana (stacks of the thylakoid) and sub-organelles, or daughter cells in which photosynthesis begins prior to the chemical reactions being completed within the stroma.
Membrane Carbohydrates – Structure, Types, Location and Functions
Membrane carbohydrates are glycans attached to proteins and lipids. Learn their structure, types, location, glycocalyx, functions, synthesis and examples.
List of Top Biotechnology Techniques
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
Biosafety Guidelines – Biosafety guidelines and regulations
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
Biosafety Cabinet – Definition, Classification (Class I, II, III), Working Mechanism, Application, Features.
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
Simple columnar epithelium – definition, structure, functions, examples
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
