The Kingdom Protista

In this lab, we examined protist survival in different communities. An biological community is a community where two or more species coexist in

Kingdom: Animalia, it's an organism who is multicellular meaning eukaryotic and can move anywhere by itself though its lifespan.

The purpose of this study is to identify four unknown organisms. The unknown organisms have been assigned randomly to six-research groups by Professor Hoffman. Each research group was provided two eukaryotes and two prokaryotes. The unknown organisms will fall into the following classifications: bacteria, algae, fungi, or protozoans. All living organisms are organized into one of three domains of life, Bacteria, Archaea, and Eukarya.

if we look at the general shape of the approaches to hacking life, there are current, consensus, six kingdoms. Which is planets, animal, fungi, protests, little things, and bacteria.

The all animals are classified under the Kingdom Animalia, also known as Metazoa. This kingdom does not contain prokaryotes. All the members of this kingdom are multicellular, eukaryotes. They are heterotrophs, they depend on other organisms directly or indirectly for food. Most of the animals ingest food and digest in the internal cavity. Most of the organisms are motile which means they can move independently and spontaneously.

KINGDOM PROTISTA: These organisms are placed here more because of what they are not than what they are. Kingdom Protista contains all Eukaryotes that are NOT Plants, Animal, or Fungi, more than 50,000 species in all. Kingdom Protista includes unicellular and a few simple multicellular Eukaryotes. Eukaryotic cells have nuclei and organelles that are surrounded by membranes.

Brachiopods were shelled animals that lived in the seas of ancient times and is commonly found in Paleozoic marine layer of the Canyon. They are made up of 2 asymmetrical shells called “valves”. One valve is longer that the other one. Bryozoans are polyp like and tiny. They form colonies that resemble corals. They form lacy structure on hard surfaces and stick structures into the water column. Crinoids resemble plant but were actually animals that looked like sea stars on a stick. They had root like structure to collect food, circulate fluid and even act like feet at times to move across ocean floor.Sponges are colony of single cells where some cells catch food with Cilia, others wander through and distribute food and some engineer the structural

Organisms are all over the place. There are two specific types of organisms that are specifically common on earth. They are the Eukaryotes and prokaryotes cells. Both the prokaryotic and eukaryotic are found where there is life. They have similarities as well as differences.

After time the hot surface of the Earth was cooled down with rain that gave formation to oceans. In oceans prokaryotes, single celled organisms , were formed. Eventually prokaryotes merged with one another to create eukaryotes, more complex single celled organisms. Prokaryotes and eukaryotes became the building blocks of all organisms.

The next phylum of animals, more complex than protozoa, is phylum Porifera (also known as sponges). Sponges are multicellular filter feeding marine animals that have cell/tissue level of organization. They are sessile, meaning they cannot move from the substratum and they have a water filled central cavity.

Some Prokaryotes live in commensalism and some in parasitism. Either way a lot of prokaryotes can get a bad reputation because we know so much about the pathogenic form of prokaryotes, that we forget that a lot of prokaryotes play a vital role in our own bodies, especially in our digestive track. Prokaryotes help break down certain gasses, compounds, proteins, and even use cell signaling to communicate with the cells in out stomach wall. Prokaryotes are vital in preforming/helping with ecological services, humans, nitrogen cycle, they even eat the dead skin off you body! This was a brief description of prokaryotes, but you could probably fill up a library with all the details about

The term ‘eukaryote’ encompasses most of the visible species on the planet. A eukaryotic cell is one who's genetic material and organelles are bound by membranes, as opposed to a prokaryote who’s nucleoid and organelles are not membrane bound and sit within the cell membrane in the protoplasm - this grouping is considered the most fundamental classifications of organisms.

Members of the kingdom Monera and Protista share various characteristics in common. However, they also differ on various features. These two groups of organisms influence human life differently since they exhibit differences in some aspects. Knowledge of the differences and similarities of the two groups can help predict the means of dealing with the problems caused by the organism. For instance, diseases caused by bacteria are treated using antibiotics. However, antibiotics are not used to treat diseases caused by Protista, for instance malaria.

In 1969 Whittaker organized a system in which five kingdoms were developed. Three of these kingdoms were added to animals and plants: Bacteria, Protista, and Fungi. Whittaker defined these kingdoms with a number of characteristics, whether the organisms possessed a nucleus (eukaryotic) or no nucleus (prokaryotic). Because bacteria are prokaryotic and virtually are all are unicellular, they are different from the other four eukaryotic. Most of the other eukaryotic unicellular organisms were placed into the kingdom Protista.

Protista life is approximately estimated to be 1.5 billion years old.Protista can be found from the depths of the ocean to the dead organisms, also as parasites in animals and plants. Protista feeds on particles dissolved in water which can be other bacteria, and because protista are incapable to move, they are found in aquatic and marine habitats such as: streams, lakes, freshwater ponds, and oceans. Protista that occupy marina habitat are the most important. Algae is a type of marine protista which produce 30 to 50 percent of the earth’s oxygen and live near water’s surface. Also algae supplies the make up of the sea floor. There are over 100,000 living species of protists.
