What is Kingdom's Protectista?

Kingdom The Protectista is a biological classification for unicellular microorganisms with eukaryotic ancestor. Referring to eukaryotic origin simply means that the organism is formed by eukaryotic cells: those cells that have a core and the surrounding membrane. Virtually all living organisms, with the exception of Prokaryotes, are formed by eukaryotic cells. The primary distinguishing factor of Kingdom Protectista is that proto -gitters are usually unicellular water microorganisms.

Organisms arranged under Kingdom The Protectist included water forms, mucilation forms, algae and similar eukaryotic unicellular microorganisms. Records suggest that the smallest organism in the Kingdom Protectist is Protists, microscopic organisms for unicellular cells such as protozoa. Protectists live exclusively in water conditions, although certain species choose exclusively freshwater, sea or water environment. A large number of protoks are parasitic, living in water tissues Host animals and plants.

For decades, scientists have organized all living organisms into five primary biological kingdoms, which were then divided into descending categories, including Phylum, class, order, family and other categories. The primary kingdom consisted of an animal, plants, mushrooms, prokaryotes or protoctist. Children at elementary school and even secondary school and universities were and often taught the biological classification of five kingdoms in scientific classes around the world.

As part of the five kingdoms scheme, Kingdom was served as the Kingdom of Exclusion. Any living organism, which was not an animal, fungus, plant or prokaryote, was arranged under the Kingdom Protectista by default. Animals and plants are formed from embryos, while mushrooms form from disputes. Prokaryotes have specific structural properties at the cellular level, the most remarkable is the lack of lack. MemberVé Kingdom The Protectist is not formed from embryos or spores and has eukaryotic cells rather than prokaryote cells, which guarantees a separate classification of the kingdom.

It was found that the discoveries of unicellular microorganisms originating in the 1960s and 1970s had multicellular derivatives. Numerous discoveries have changed the way some scientists perceived an old program of five kingdoms. Since the 1970s, some biologists, zoologists and other scientists have been involved in the new scheme of multi-kingdom classification. In fact, many such scientists have decided to use various multi-kingdom schemes received by certain segments of the scientific community.

One argument in favor of the reworking of the historical understanding of Kingdom's Protectista is the discovery of unicellular organisms with multicellular derivatives. Some of these derivative organisms meet the criteria for plant phylum. Other discovered organisms show that such unique tissue structures compared to Kingdom Protectist members that sciencesCI claims that these organisms deserve a separate classification of the kingdom.
