The 5 Kingdoms of Life
The 5 Kingdoms of LifeMONERA
The Monera Kingdom, though not often recognized by all people, has a profound effect on all of our lives. Its cell structure is simple, containing one or a colony of cells. It has no nucleus, no organelles, a cell membrane, and only certain members of the kingdom have a cell wall. They most often obtain food by photosynthesis or feeding off another dead organism. It can move only through water or the organism that is hosting it. It reproduces not sexual or asexually, but through conjugation and fission. It is environmentally important because of its significance to the food chain. It also produces nitrogen, vitamins, and antibiotics, essential to several other types of life. Some practical examples of this kingdom are bacteria and cyan bacteria.(Smith, E. 1998, Hall, S. 1996, LRC 1997, SER 1998)
PROTISTA
The Protista kingdom is another kingdom often overlooked in scientific importance. Its cell structure is somewhat more complex than that of the Monera. Most of its components are single-celled organisms, however some are multi-celled. Its cells consist of a nucleus, organelles, vacuole, cell membrane, and some of them also contain a cell wall. It uses many intricate processes to obtain food, such as pseudopodium, photosynthesis, cilia, flagella, as well as photosynthesis. It moves by means of cilia, flagella, and pseudopodium. It can reproduce by conjugation, fission, asexual, and sexual means. In the environment, it produces much the way plants do, while consuming much the way animal do. It is important to its habitat because it stabilizes the food chain, is a human food source, and produces oxygen. Some common protista are plankton, algae, and the amoeba. (Smith, E. 1998, Hall, S. 1996, Southron, F. 1996)
FUNGI
After careful examination, you will realize that the fungi kingdom is more than just mushrooms. Most of its organisms are single-celled, with some exceptions being multi-cellular. This group has a nucleus, organelles, a cell membrane, as well as a cell wall present in...
