Living organisms consist of millions, billions or trillions of cells. ... Other organisms, however, have only one cell in their entire body, and humans can see some of these single-cell organisms with the naked eye. Human egg cells, unusually large bacteria, some amoebas and squid nerve cells make up this list.

Bacteria are single-celled microscopic organisms that are characterized by the presence of incipient nucleus and few membrane-less cell organelles. Fungi, singular fungus, are eukaryotes that are characterized by the presence of chitin in the cell wall.

All life can be classified into three domains: Bacteria, Archaea, and Eukarya. Organisms in the domain Eukarya keep their genetic material in a nucleus and include the plants, animals, fungi, and protists.

Linnaeus later classified all living organisms into two kingdoms – Plantae and Animalia. Whittaker proposed an elaborate five kingdom classification – Monera, Protista, Fungi, Plantae and Animalia.

Bacteria are single-celled, living organisms. They have a cell wall and all the components necessary to survive and reproduce, although some may derive energy from other sources. Viruses are not considered to be “living” because they require a host cell to survive long-term, for energy, and to reproduce.

Organisms can be classified into one of three domains based on differences in the sequences of nucleotides in the cell's ribosomal RNAs (rRNA), the cell's membrane lipid structure, and its sensitivity to antibiotics. The three domains are the Archaea, the Bacteria, and the Eukarya.

A bacterium -- more commonly seen written in its plural form, bacteria – is a tiny, single-celled organism. Bacteria can exist on its own in the world, or inside of other living things: plants, animals, you, me. Not all bacteria are bad, though, and we have beneficial bacteria living inside our bodies every day.

Taxonomy is a scientific system that classifies organisms into categories based on their biological characteristics. ... This method of defining species is called phylogenetics, which is the study of the evolutionary relationships among organisms.

An organism is an individual living thing. It is easy to recognize a living thing, but not so easy to define it. Animals and plants are organisms, obviously. Organisms are a biotic, or living, part of the environment.

An organism is an individual. A species is a collection of individuals with a very large number of common genes. The concept of species is (among other functions) used to expedite talking about individuals.
