MONERA
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 all fungi that is absent from the previously mentioned kingdoms. It obtains food in majority from absorbs ion, partnership, and leeching from decaying organisms. Its only movement is that of the host; which it is connected to. They reproduce by spore, as well as by asexual budding. They are helpful because they produce antibiotics and also help in fermentation. Some organisms that are members of the fungi kingdom are mushrooms, molds, mildews, and yeast. (Smith, E., 1998, Hall, S. 1996, Lista, D. 1998)
PLANTAE
The planate (more commonly plant) kingdom holds some interesting properties. Unlike the previously mentioned kingdoms, the planate consists only of multi-celled organisms. All members of the group known as planate contain a nucleus, organelles, cell membrane, cell wall, as well as a vacuole. Their major source of food comes from the process of photosynthesis. Its only movement is in growth, where it gravitates toward the most prominent light source. It reproduces through a complex process of Propagation, which consists of grafting, budding, cutting, and layering. It is used in its envierment for a food source as well as a medicine. Angiosperms, gymnosperms, mosses, and ferns all call the planate kingdom their kingdom.( Smith, E., 1998, Hall, S., 1996, USDA, 1999)
ANIMALIA
We finally reach the kingdom which we as human beings call home, the kingdom more commonly known as the animal kingdom. The Animalia and Planate kingdoms are the only two which consist exclusively of multi-celled organisms. The cells of a member of the animalia kingdom consist of a nucleus, organelles, cell membrane, as well as the vacuole. They obtain food mainly from preying on another species or consuming a previously deceased organism. They have muscular movement through water, air, and soil. Its main role in the envierment is consumers. However, they also provide an important food source for other members of its kingdom. Some Animalia kingdom members are mammals, amphibians, sponges, and worms. (Smith, E., 1998, Hall, S., ,1996
