Microorganisms are virtually everywhere; found in diverse environments, both living and non-living.

Macroscopic features of a bacterial colony including size, shape, elevation, margin, texture, and color.

Patterns of microbial growth in a liquid medium, such as turbidity, sediment, pellicle, or flocculence.

Techniques, such as using sterilized equipment, to prevent contamination when transferring cultures.

A method to obtain isolated colonies by diluting a bacterial sample over an agar plate surface.

An optical instrument that uses visible light and a system of lenses to magnify small objects or structures.

Process of determining the relationship between divisions on the ocular micrometer and the stage micrometer.

Observing features (cell shape, structures) of microorganisms like fungi and protozoa under a microscope.
