How To Clean Sediment From A Teapot

Kingdoms of Life Biodiversity

Life. In the beginning, life is a dynamic concept, a concept that changes among other reasons depending philosophical and points view, research and discoveries. To define what life is as complex as life itself.

be alive, what is a living being?. At what point of composition and chemical and physical interaction of molecules and let life begin its inert state matter, and to become defined as living matter?.

Living things require energy, feed, occurs in these processes of energy exchange, consumption and release of energy. Living things grow, change, grow, interact with the environment and have the ability to reproduce.

Life on Earth is an action that occurs in variety, ecological complexes and ecosystems. Life ends up being a compendium of curiosities that attracted attention to the man since his first walk.

Biodiversity. The concept of biodiversity encompasses all the varied forms of manifest life and their relationship, thereby including ecological systems. Roughly biodiversity can be divided into three levels: ecosystems, species and genes. Biodiversity manifest today is the result of dynamic and evolving, the interconnectedness of species, ecological changes and genetic variations that are displayed on the existence and living forms of matter.

Biodiversity and a little history of its classification:

Since Aristotle met living organisms into two kingdoms: Animal Plant and is now even easier for us to differentiate the bodies separating life that way, but there appear then the great confusion as to call a coral plant simply by having, at first glance, form branched tree way, this case is typical and occurs in some animals that live in colonies.

Ernst Haeckel (XIX century) created a third kingdom to group certain tiny creatures which generated much discussion at the time of classifying animals and plants, these unicellular organisms grouped in the kingdom Protista with intermediate similarities between plants and animals.

Carl von Linnaeus (1707-1778), a student of botany was born in Sweden and is considered the father of taxonomy, categorized a large group of species thus establishing divisions to group them for study. Many of these categories are used today.

Linnaean classification was based on the principle that plant and animal species living unit were the lower and higher categories grouped into generic.

Linnaeus calls this type of grouping or classification binomial nomenclature used and Latin, the language learned at the time, to name the different species and genera was classified, thus establishing a scientific language adopted internationally.

In a fourth kingdom shall be on the bacteria and a type of organisms called blue-green algae or cyanobacteria, for prokaryotic cells present is say no nucleus or organelles defined, Kingdom Monera.

remained to place the mushrooms in a large group and not even look like plants, have eukaryotic cell with its nucleus and cell walls but lacking pigment defined photosynthetic as enshrined in the United Plant and were placed then in a fifth kingdom by the American scientist RH Whittaker, calling Kingdom Fungi, this just in 1969.

Finally, most of the scientific world today uses these five kingdoms RHWhitaker proposed to classify the world of biological diversity: Monera , Protists, Mushrooms, Plants and Animals . (see Margulis & Schwartz, 1985)

the God eternal, wise and powerful as I've seen him walk past me and I remained confused. I found some traces of his footsteps in his works, even in the smallest. What wisdom! What power! It is inexplicable perfection!
