Unicellular organisms colorful kingdom
According to belief, single-celled organisms were first inhabitants on Earth, and their colorful world is deservedly called the kingdom by scientists. The oldest microorganisms are considered to be bacteria and archaea. In fact, Colorful single-celled animals and prokaryotes were discovered by Antonie Philips van Leeuwenhoek – a Dutch tradesman and scientist, known as “the Father of Microbiology”. A unicellular organism consists of only one cell. These organisms live together, and each cell in the colony is the same. However, each cell must carry out all life processes in order for that cell to survive. In contrast, even the simplest multicellular organisms have cells that depend on each other in order to survive. Most unicellular organisms are of microscopic size and are thus classified as microorganisms. However, some unicellular protists and bacteria are macroscopic and visible to the naked eye.
