Kingdoms of Life Essay

On our planet earth we have what argon c eached earths, 5 to be exact, consisting of a very diverse base of living things. utilise these five acress we classify our species and organize information on what we be and what resides with us. When we shoot for perpetuallyy living creature into one of the five kingdoms it better helps us understand the world around us and its habitants. The five kingdoms accept Moneran, Protist, Fungi, kingdom Plantae, and the one we call home, animalia.1. Monera The simplest of all organisms is the bacteria of the Moneran kingdom. They argon broken d hold into two types Eubacteria and archaebacterium. Eubacteria is known as the true bacteria which makes up the roughly 10,000 species in the Moneran group. Archaebacteria or ancient bacteria if you will, is the minority of the group and atomic number 18 whole found in extreme milieus including but non limiting swamps, salinity lakes, deep-ocean hydrothermal vent, etc. there are many types of s pecies belonging to the Moneran kingdom that have yet to be discover. Monerans are also the only group within the five kingdoms that are all prokaryotes. Prokaryotes are one-celled or colony of cells.2. Protista In this kingdom we have multi cellular organisms (Protista) which are not a part of nor do they fit, the Animal, Plant, or Fungus domain. In the beginning, phylum Protozoa were placed in a sub-kingdom of Animalia but because of the problems this classification had, it later(prenominal) became its own kingdom. All members of this phylum have what are known as nucleated cells and live in aquatic habitats (both freshwater and marine). According to Lynn Margulis, K.V. Schwartz and M. Dolan (1994), the cells of all Protoctista originally formed by bacterial symbioses or symbiogenesis. Members of this kingdom are not considered animals because they do not come from an embryo, they are not plants nor are they considered fungi because they do not develop from spores.3. Fungi at t hat place are some members of the Kingdom Fungi that are associated with algal cells of the Kingdom Protista and/or prokaryotic cyanobacteria of the Kingdom Monera. Fungi plays a very critical role in natures continual rebirth Fungi actually recycle all dead original matter turning it into useful nutrients. Fungi consits of species like mushrooms, molds, mildews, stinkhorns, rusts, puffballs and many others. There are on estimate 100,000 known species today with hundreds of new species be discovered each year.4. PlantaeWith over 1.6 million species of living organisms on earth and new species discovered alwaysy single day, in extra insects and nematodes residing in rsecluded tropical regions. However, with the present rate of destruction, a majority of the complete(a) tropical rain forest are headed straight for extinction, leaving millions of species undiscovered by the human race. It is the theory that approximately 99 percent of species that ever resided on earth were extin ct long before the human ever set foot on this planet. Even with humans having such an tall(prenominal) significance to the development of earth, technically they are considered to be newcomers on this grand planet. If all theories are correct, earth is aged at about 4.5 meg years old, meaning the ancient life forms (such as the cyanobacteria) appeared roughly 2-3 jillion years ago. 5. AnimaliaThere are nine phyla of this kingdom including the pursuance Porifera (poriferans), Cnidaria (cnidarians), Platyhelminthes (flatworms), Nematoda (roundworms), Annelida (annelids), Mollusca (molluscs), phylum Arthropoda (arthropods), Echinodermata (echinoderms) and Chordata (chordates). Animals are considered to be part of this group because they are all multi-cellular organisms whose cells are connected by a plasma tissue layer and not by a cell wall of cellulose like the others.The differences amongst plants and animals led to the division of all life into what is known as (referenced a bove) Plantae and Animalia. In animals, the cells are organized into tissues and specialized tissue systems that permit them to head for the hills freely in search of food. They build energy by getting and ingesting their food, unlike plants, which use the system photosynthesis to benefit from the nutrients they need to abide. A wholesome developed nervous system with sensory and motor nerves is what enables animals to turn around environmental stimuli as well as a response to the environment around them. It was found that some were plant like while others (protozoa) resembled animals in that they obtain locomotion by means of flagella and that they actually digest food.The Animal Kingdom holds the most species of all of the kingdoms, ringing in a lower-ranking over one million. Interesting fact, is that more than half of the animal species are insects. The result of 300,000 beetles plus the 800,000 different insect species a make up the largest order of insects (one fifth of all speciesusing a total of 1.5 million). It has been verbalise that if the species among plants and animals on earth were lined up at random, any 5th species would be a beetle.VirusesViruses are out of the Kingdom sort completely and sometimes they are said even to belong to their own kingdom, the kingdom Virus. The small and less complex infectious agent is do of tiny macromolecular units composed of DNA or RNA covered by an outer protein coat. Virus do not contain membrane-bound organelles, ribosomes, a cytoplasm, or any other source of energy formation of their own. They do not have the self-maintenance metabolic reactions of living systems, they lack cellular breathing and gash exchanges. They are completely capable of reproducing but only at the expense of a host cell. They can and will only survive as minute macromolecular particles outside of their body. Plant viruses are transferred between each other by insects that feed on sap, such as aphids, while animal viruses c an be carried by blood-sucking insects (mosquitos for instance).http//www.biology-questions-and-answers.com/life-kingdoms.html
