Colony Forming Units (CFUs) are a measure used in microbiology to estimate the number of viable bacteria or fungal cells in a sample. They are calculated based on the number of colonies that form on a culture plate, with each colony presumed to originate from a single cell or group of cells.

Fungal cells are eukaryotic, meaning they have complex structures enclosed within membranes, including a defined nucleus and organelles like mitochondria. A unique feature of fungal cells is their cell walls made of chitin, a strong, flexible, and nitrogen-containing polysaccharide, distinguishing them from plant cells which have cell walls made of cellulose.

Microbiology is the scientific study of microorganisms, which are tiny life forms such as bacteria, viruses, fungi, and protozoa. It plays a crucial role in understanding infectious diseases, biotechnology applications, and the ecological impact of microorganisms on the environment.

A culture plate is a flat, round container used in laboratories to grow and study microorganisms, such as bacteria and fungi, under controlled conditions. It provides a sterile environment and nutrient-rich medium to support the growth and observation of microbial colonies for research and diagnostic purposes.
