Science how many kingdoms

Fungi Fungi are usually motionless organisms that absorb nutrients for survival. Plants Plants contain chlorophyll, a green pigment necessary for photosynthesis, a process in which plants convert energy from sunlight into food. Animals Animals are the most complex organisms on Earth. More about Animals. See also:. Five Kingdoms of Life.

The number of subdivisions listed by G. Lecointre and H. Guyader for each domain are shown in parentheses. See Archaebacteria: Life On Mars? The discovery of a virus called "mimivirus" in complicates the placement of viruses in the overall classification scheme for living organisms. Whether mimivirus should be placed in an existing domain superkingdom , or in its own domain, remains to be seen.

Prior to this discovery, viruses were generally considered nonliving until they hijack a living cell. Officially, this virus got its name because it mimics bacteria in size and complexity. Mimivirus was found inside an amoeba within a cooling tower in Bradford, UK. In fact it is larger than the bacterium causing gonorrhea. The virus genome contains 1. The bases make up 1, genes, which makes it as complex as some bacteria.

In addition, mimivirus can make about of its own proteins, and can even repair its own DNA if it gets damaged. Normal viruses are not capable of protein synthesis or DNA repair on their own, they must rely on the organelles of their host cells for these activities. For more information, see D. Raoult, et al.
