Protists are members of Protista, one of the five main kingdoms of organisms. They are eukaryotic, multicellular and unicellular creatures that are either microscopic or very large in size, and are found in moist and marine environments. Being mostly micro in size, 5 micrometers to 2 to 3 millimeters is the prevalent size for protists. Despite not being categorized in any other animal kingdoms due to their complex structures and heavy diversity, they still are very much like fungi, animals and plants
protoplasm(the plasmodium)feeding on bacteria, spores, and other organic matter, much like an amoeba does. When conditions become unfavorable , the plasmodium changes, taking on the appearance of a fungus. There are two major types of slime molds in the Protist Kingdom. The first kind are the Plasmodial slime molds or true slime molds. They are a rather large singled celled mass with thousands and thousands of nuclei called a plasmodium. They form when individual flagellated cells gather together in a bunch
Dictyostelium discoideum is an amoeba in the class Dictyostelia which is a group of cellular slime molds, also known as social amoebae. Their life cycle begins when they hatch from spores into myxamoebae. In this stage they are unicellular amoebae that reproduce by mitosis. Mainly found in soil these amoebae have a very short life cycle, only 24 hours long. Dictyostelium discoideum have 3 methods of reproduction; mitosis, sexual reproduction, and asexual reproduction. The first method is carried
Background Info: Mold is a group of fungus that are a decomposer in nature. They are basically a single celled organism with thousands of nuclei. They nearly have the same life cycle as fungi. They are made up of filaments, called hyphae.They can be found in shady, damp areas outdoors, like rotting logs, or any place with decomposing vegetation. There are also parasitic molds, that live off a host. . Mold can reproduce with itself, asexually, and with other molds, which would be sexual reproduction
Introduction: Euglenas are unicellular organisms classified into the Kingdom Protista, and the Phylum Euglenophyta. All euglena have chloroplasts and can make their own food by photosynthesis. They are not completely autotrophic though, euglena can also absorb food from their environment; euglenas usually live in quiet ponds or puddles. (Biologycorner.com, 2016) Euglena is a interesting specie because they are combination of plant and animal. They can feed themselves through photosynthesis like a
Both prokaryotes and protists have negative and positive impacts on humans. Prokaryotes and protists are both used in a variety of ways by humans today. They can affect humans in the way of disease, which can be deadly, but also help humans with environmental issues too. Also, both provide food sources for humans which are beneficial. Most prokaryotes are bacteria, which can cause many human diseases. In fact, bacteria cause about one half of human diseases (Reece et. al, 2011 p583). Some examples
Protists were a dominant form of life on Earth 1.5 billion years ago (Laybourn-Parry). A protozoa, a eukaryotic organism, has existed from the beginning of time and in various environments and conditions, such as hot and cold water. Their success is mainly due to their ability to adapt to their environments. Protists are mixotrophs, meaning that they are capable heterotrophy (secondary energy derivation through the consumption of other organisms) and autotrophy (primary energy derivation
Protists and prokaryotes serve as the primal foundation for the evolution of life present on Earth today. This is exemplified through the endosymbiotic theory, which gave rise to eukaryotic cells, as well as development of photosynthetic processes in plants. Despite the two being quite similar, they also possess key distinguishing features. For instance, the primary difference is that prokaryotes are strictly unicellular organisms, meanwhile protists are able to assume a variety of both multicellular
Introduction Protists are not animals, plants, or fungi. They have their very own kingdom called The Kingdom Protista. Protists are a very diverse group. There are over 200,000 of them. They get classified into three main groups, and then get classified further into phyla Protists can be found in everyday surroundings, and they have a big impact on all organisms on Earth. Research All protists are eukaryotes and their DNA is found within the membrane-bound nucleus. They can be unicellular or multicellular
Our planet, the Earth, is the third planet from the Sun, and usually is known as the Blue Planet. Its location in the Solar System and the particular characteristic of being the only planet with abundant water, have made possible the development of life here. Thousands of millions of years ago, the first living organisms evolved from a non-living matter, and since then the Earth has been inhabited by many different species. Those, who have dedicated their research to study and classify living organisms
Xenophyophores Deep sea is the largest ecosystem on Earth and it exhibited a large diversity of life forms that appeared to be bizarre and curious to both general and scientific communities. The sediment samples obtained from deep seas were usually containing fecal pellets (released by animals lived in photic zone of ocean), foraminiferan tests, as well as organic matters. Recently, during the July of 2011, researchers with Scripps Institution of Oceanography at UC San Diego and National Geographic
In the fourth lab completed in Biology 101, we discovered more about the cell. I learned that the cell is the basic structural and functional unit of life. The cell theory states that are composed of cells and that all cells arise from preexisting cells. There are unicellular organisms such as E. coli and multicellular organisms that are composed of more than one cell. In this lab, we discussed the importance of the cytoplasm and the basis of DNA. We used microscopes to observe prokaryotic and eukaryotic
My favorite organism is amoeba. Amoebae (plural amoeba) are protozoans that belong to Amoebozoa kingdom. They consist of single celled organisms that have no definite shapes. These organisms are categorized as protist, a group of neither animals nor plant. Because Amoebae are mostly very tiny organism, microscope is needed to observe them while some are large enough to be observed with naked eyes. The most widely known Amoeba is probably Amoeba proteus. It sizes approximately around 0.028 inches
methane by the process of metanogenesis. The relationship between Archaea and protists (eukaryotic microorganisms) inside the gut of the termite is essential for the digestion of cellulose and enhance cellulose fermentation. Hydrogen and carbon dioxide are produced by protists, and can be used by Archaea as a source of energy. Methane is formed as a byproduct of this process, the elimination of the hydrogen enables the protists to maintain an optimal pH to for favourable conditions for decomposition to
In sexual reproduction the male and female cells fuse, to produce spores inside a fruiting body. In asexual reproduction they reproduce by simply making little copies of themselves. Protists are single celled eukaryotic organisms that are able to reproduce asexually and sexually. During sexual reproduction, two protists join and exchange genetic material in the nucleus. Prostist make people ill when they become human parasites they infect via puncture wounds and through consumption of contaminated
Antonie van Leeuwenhoek was a scientist and was best known for his contributions to microbiology; he received the title of "the Father of Microbiology” and dedicated many years of his life to improve the microscope in order to attain incredible heights of precision of the microscopic lenses. He produced magnifications from up to 275X, with a resolving power of up to 1.4 µm. Moreover, he presented his findings from the material of animals and vegetables in extraordinary detail as well as being the
structurally advanced of the major cell types. Describe the structure and function of each of the eukaryotic organelles. Distinguish between those that are and are not membranous. Most are membranous. Eukaryotic cells, whether from animals, plants, protists, or fungi, are the most structurally advanced of the major cell types. Eukaryote are single-celled or multicellular organism whose cells contain nucleus and any other structures (organelles) enclosed within the membrane that perform specific functions
Hydrogen Peroxide is then broken down into water and oxygen. Valcule and vesicles are a large storage sacs that store water, and sugar. Valcule are larger in plants and take up 90% of the cells space. Protist located in the valecules pump out things so the valecule does not explode. Lysosomes are digestive organelles. Lysosomes eat any damaged organelles and waist. Lysosomes contain digestive organelles. If it was to bust it would kill the cell do to its
immigrated to the U.S. and created settlements all around the country. To provide for themselves in these settlements, most of the people farmed the land because that was what they knew how to do. The primary cause of this famine was a fungus-like protist called Phytophtera infestans that attacked Ireland’s potato crop, causing them to rot. Unfortunately, the people of Ireland
live at temperatures less than -20 degrees Celsius to temperatures hotter than the boiling point. These tiny organisms include Bacteria, Archaea, Fungi and Protists. Bacteria and Fungi are a commonly known form of microbe unlike Archaea which are similar to bacteria but appear to have some traits which are not present in any true bacteria. Protists include different types of mold and algae. Fungi are eukaryotic organisms which are either single-celled or multi-cellular organisms, their DNA containing
