Eubacteria do not have nucleus and cell organelles. They have single circular DNA and numerous plasmids (small circular pieces of DNA) in cytoplasm and cell wall made of chains of peptidoglycan. Additional layer of lipids and sugar around the cell wall can be found in Gram negative bacteria (term "negative" refers to their inability to absorb Gram stain that is used for dyeing of bacteria). This type of bacteria is harmful for humans and animals due to potent toxin (endotoxin) incorporated in the lypopolysaccharide layer.

Cultured meat is meat produced in vitro, in a cell culture, rather than from an animal. In production, cultured cells are capable of multiplying so many times in culture that, in theory, a single cell could be used to produce enough meat to feed the global population for a year.

Males and females release their reproductive cells directly into the water. Females are able to produce 1 million eggs per season. Fertilized eggs float on the surface of water like a huge veil (all eggs are arranged in a single layer). 1 to 3 weeks later (depending on temperature), larvae emerge from the eggs.

Non-food agriculture uses apply to things like the creation of plants to produce plastics, and enzymes or single-celled organisms for industrial fermentation and the production of textiles.

The human body is only made up of 43% "human" cells. The other 57% is comprised of bacteria, fungi and single-celled eukaryote. Bacteria far outnumber fungi and other microbes, and most of these microbes are found in the gut, thus almost all of the 57 percent are intestinal bacteria.

The algae Caulerpa taxifolia is comprised of a single cell several meters in length. It challenges some of the corollaries of cell theory, e.g. the idea that organism-level properties are an emergent property of cellular phenomena. The concepts like “tissue” and “organ” begin to lack meaning.
