How Many Kingdoms Of Life Exist?

Introduction

Kingdom of life is a dynamic concept, a concept that changes among other reasons depending on philosophical grounds and views, research and discoveries. This kingdom of life defines the life as a complex life itself.

Living things require energy, occurs in these exchange processes energy consumption and energy release. Living things grow, change, and interact with the environment and have the ability to reproduce. Life on our planet is action occurring in variety, based on ecosystems and ecological complexes. Life ends up being a compendium of curiosities that attracted attention from early man step.

Biodiversity

The concept of biodiversity encompasses all the various forms of manifest life and its interface, thus including ecological systems. Biodiversity can be divided into three levels: ecosystems, species and genes. Biodiversity is the result of the dynamic and evolving process, the interrelationship of species, ecological changes and genetic variations shown in the existence and living forms of matter.

Kingdom of Life History

Since Aristotle met living organisms into two kingdoms: Animal and Plant, even today it is easy for us to differentiate the bodies separating life that way, but then there is a great confusion as to call a coral plant simply by having a first glance, it forms a branched tree way, this case is typical occurs in some animals that live in colonies. Later on Ernst Haeckel (XIX) created a third kingdom to group it consist of certain tiny living things that generated much discussion while classifying animals or plants, these unicellular organisms grouped in the kingdom Protista, with intermediate similarities between plants and animals (VALLIN 1966 pp. 67-98).

Monera

Bacteria belonging to the United or Monera, one of the five kingdoms that are grouped in the various creatures that inhabit our world, according to the classification used and accepted internationally, This Kingdom is made ??up not only by bacteria, it is also named as blue-green algae.

This Kingdom rich in species diversity, grouping organisms called prokaryotes by having a named prokaryotic cell type it has a lacking, which is core surrounded by membrane. In laboratory studies have determined that only one circular chromosome exist, it has been observed by electron microscopy corroborates and the absence of organelles surrounded by membranes. Members of this kingdom are considered the first inhabitants or forms of life on Earth, scientific research argue that existed 3.5 billion years ago is that might be prevailing in the early atmosphere (STERN 2003 Pp. 41-54).

The Monera are unicellular, autotrophic or heterotrophic, can be found in every room, some bacteria are found in surprising places like Thermophile bacteria, the bacteria can be stationary or mobile, have the rigid wall and reproduction is a sexual, but can have genetic information exchanges between individuals of the same species or different species. They can be photosynthetic or chemosynthetic. Among the latter are the saprophytes that cause putrefaction to ferment and parasitic pathogens.

Protista

The Kingdom Protista includes eukaryotes, are mostly unicellular or multi cellular colonies forming, heterotrophic or autotrophic and ...
