Transcript of Protist kingdom
in 1866. Protists don't have specialized tissues, while all of the other groups do. Protists are incredibly diverse, one way to classify them are according to the way they obtain nutrition. Protists that are heterotrophs are called animal like protists, whereas those that produce there own food by photosynthesis are plant like. Those who obtain their food by external digestion are called fungilike protists.
Species: proteus, animalcule, dubia, animalcule, etc.
classification The amoebas don't have a fixed body-shape and they appear to be like blobs of jelly-like substance. By constantly changing its body shape, the amoeba creates body extensions known as pseudopods which help in locomotion. notable features pseudopod
method of movement They are found in many different types of wastewater, including activated sludge and trickling filters and lagoons. Amoebae grow well on particulate organic matter and are able to tolerate low D.O. environments. Testate amoebae are often found in lightly loaded plants or in plants where nitrification occurs. They are usually found in young sludge ages but they can be found at any age if all of a sudden a high BOD loading has occurred. They can be found during plant start-ups or often following upsets. They can be used as an indicator for a process control tool. Amoebae can tolerate low D.O. environments.
enviroments PARAMECIUM PARAMECIUM CLASSIFICATION Domain: Eukaryota
Paramecium are members of the phylum Ciliophora. They share many common characteristics with the rest of their phylum, but are also unique. For example, their shape is quite different from that of many other Ciliophora. They are also famous for their predator-prey relationship with Didinium. Paramecium are known for their avoidance behavior. If an encounters a negative stimiulus, it is capable of rotating up to 360 degrees to find an escape route.
NOTABLE FEATURES CILIA medium warm pond water EUGLENA Domain: Eukaryota
CLASSIFICATION NOTABLE FEATURES the Euglena is a spindle-shaped organism. Each organism has a single anterior flagellum attached to it. A shape-sustaining pellicle covers the body of the euglena. A small gullet enlarges into a reservoir which resembles a human mouth at the anterior end. Although the reservoir looks like a mouth, it is thought that euglenas probably do not ingest food through thus. A small, red, light-sensitive eyespot is located near the reservoir. A large nucleolus is incased inside a small nucleus. It is a single celled organism.The euglena has a contractile vacuole, like most protist, which has the job of maintain organism's water balance by expelling excess water from the cytoplasm into the reservoir.
AMOEBA Flagellum Euglena are found in aquatic environments, almost always freshwater ponds. Domain --- Eukarya
Kingdom - Chromalveolata
Division --- Heterokontophyta
Class ------ Chrysophyceae Planktonic chrysophytes are motile, and swim with the aid of two flagella –
although in many species the second of these may be reduced to only a short stub.
An eyespot may be present in the cell near the base of the flagella. two flagella Chrysophytes are predominantly found in fresh-water environments, although some are marine, and a few are reported from soil or snow. DIATOMS Domain: Eukaryota
Class: Bacillariophyceae A characteristic feature of diatom cells is that they are encased within a unique cell wall made of silica
Most diatoms are unicellular, although they can exist as colonies in the shape of filaments or ribbons They are non-motile, or capable of only limited movement along a substrate by secretion of mucilaginous material along a slit-like groove or channel called a raphe. Being autotrophic they are restricted to the photic zone Found in almost every aquatic environment including fresh and marine waters, soils, in fact almost anywhere moist. Domain: Eukarya
Phylum: Dinoflagellata The two flagella on dinoflagellates have a different appearance. The transverse flagellum goes around the organism's entire body in a circle. The other is perpendicular to the transverse flagellum. The action of both of these flagella in concert gives the dinoflagellate a spiral motion as it moves in the water.
They have two flagellum one longer than the other. Dinoflagellates can occur in all aquatic environments: marine, brackish, and fresh water, including in snow or ice. green algae Domain: Eukaryote
Species: aplanospora it is green. green agae moves while drifting with the waves currants. algae are prominent in bodies of water, common in terrestrial environments and are found in unusual environments, such as on snow and on ice. Seaweeds grow mostly in shallow marine waters, under 100 metres; however some have been recorded to a depth of 360 metres. slime mold Domain: Eukarya
Species: Physarum polycephalum
Slime mold takes many forms. The most common forms on turf resemble small purple or black balls attached to blades of grass, or a readily noticeable creamy-white, yellow-orange, purple, or gray jelly-like mass sitting on the lawn. The colonies of slime mold living on logs and bark mulch can be bright colors of yellow, orange or red. they move like amoebas A bright yellow slimy blob is commonly seen in the summer on mulched flower beds.
