Microorganisms Overview

Study Notes

Microorganisms

Microorganisms are forms of life (organisms) that are too small to be seen with the naked eye.
They require magnification using a microscope to be observed.
Also known as microbes.
These organisms include bacteria, archaea, fungi, protozoa, and some algae.
They play crucial roles in various ecosystems, including decomposition, nutrient cycling, and food production.
Their size varies considerably, but they are generally microscopic.
They exist in diverse environments, from soil and water to the human body.
Their study is crucial to understanding many biological processes.
Bacteria are one of the most common types of microorganisms.
Archaea are another type of single-celled microorganisms that are genetically distinct from bacteria and eukaryotes.
Fungi play essential roles in decomposition and nutrient cycling in ecosystems.
Protozoa are single-celled eukaryotic organisms.
Some algae are also considered microorganisms, and they are photosynthetic organisms that play key roles in aquatic ecosystems.
Many microorganisms are essential for life on Earth, participating in processes such as digestion, decomposition, and nutrient recycling.
Some microorganisms can cause disease in humans and other organisms while others are beneficial and even essential for human health.
They are found everywhere on the planet: in soil, water, air, and even within other living organisms.
Microbiology is the scientific study of microorganisms.
Understanding microorganisms is crucial to addressing many current and future challenges, including disease, food production, and environmental contamination.
A form of life (organism) that is so small (micro) it can be seen only with a microscope. Also known as a microbe. (This reinforces the definition previously provided.)
