Protist and Fungi Centers Station 1 Organism Ulothrix zonota 2 Diatoms 3 Spirogyra 4 Volvox 5 Euglena Name ____________________________________________Block______ Information/Questions Ulothrix is a genus of Kingdom: Protist filamentous green algae, Division: Chlorophyta generally found in fresh Class: Ulvophyceae and marine water. Its cells are normally as Order: Ulotrichales broad as they are long, Family: Ulotrichaceae and they thrive in the Genus: Ulothrix low temperatures of spring and winter. They become attached to surfaces by a modified holdfast cell. Reproduction is normally vegetative. Diatoms are a major group of eukaryotic algae, and are one of the most common types of phytoplankton. Most diatoms are unicellular, although some form chains or simple colonies. A characteristic feature of diatom cells is that they are encased within a unique cell wall made of silica. These walls show a wide diversity in form, some quite beautiful and ornate, but usually consist of two asymmetrical sides with a split between them, hence the group name. Spirogyra is a genus Kingdom: Protista of filamentous green Division: Charophyta alga of the order Phylum: Chlorophyta Zygnematales. It is commonly found in Order: Zygnematales freshwater areas. They Family: Zygnemataceae can sexually Genus: Spirogyra reproduce by conjugation. Volvox is the most developed in a series of genera that form spherical colonies. Each Volvox is composed of numerous flagellate cells on the order of 1000-3000 in total, interconnected and arranged in a hollow sphere. The cells swim in coordinated fashion, with a distinct anterior and The cells have eyespots, more developed near the anterior, which enables the colony to swim towards light. The name comes from the Greek words εὔ (eu) and γλήνη (glēnē), meaning good eyeball, referring to their light-sensitive eyespots used to direct themselves towards light. Over 1000 species of Euglena have been described. Why could Euglena be considered both plant-like and animal-like?

What type of structure do they use to move? Anabaena is a genus of filamentous cyanobacteria, or blue-green algae, found as plankton. It is known for its nitrogen fixing abilities, and they form symbiotic relationships with certain plants, such as the mosquito fern. They are one of four genera of cyanobacteria that produce neurotoxins, which are harmful to local wildlife, as well as farm animals and pets. Trypanosoma brucei is a notable parasitic species of Trypanosoma. The species causes African trypanosomiasis (or sleeping sickness) in humans and animals in Africa. The entirely parasitic species has two hosts - its insect vector and mammalian host. Because of the large difference between these hosts the cell undergoes complex changes to facilitate its survival in the insect gut and the mammalian bloodstream. It also features a unique and notable variable surface glycoprotein (VSG) coat in order to avoid the host's immune system. The Amoeba proteus is a large protozoan and belongs to the Phyllum Sarcodina. It has an ever changing shape . It can almost be seen with the naked eye. What structure does the amoeba use to move? Paramecium caudatum cannot survive without the macronucleus and cannot reproduce without the micronucleus. Reproduction is either by asexual binary fission or occasionally by conjugation (sexual). During binary fission a fully-grown organism divides into two daughter cells. Conjugation consists of the temporary union of 2 organisms and the exchange of micronuclear elements. Without the rejuvenating effects of conjugation a paramecium ages and dies. Saccharomyces cerevisiae is a species of budding yeast. It is perhaps the most important yeast owing to its use since ancient times in baking and brewing. Make your own live slide from the flask of growing yeast. Try to find evidence of budding. . 13 Rhizopus nigricans Rhizopus nigricans is a type of black mold which is known to grow on bread, therefore known as breadmold. It is a known producer of allergens.

Make sure to include the magnification on your drawings. Then use the Pond Identification Kit web site to identify your organism. Write the name of your organism on the line above your drawing. In the box below your drawing write a short description of your organism. 17 Go to the Smallest Place on the Web website and do some exploring. Answer the following question? Can a whole ecosystem and food web exist in a small “cup” of water? Explain!!!! What types of organisms are producers? Who are the consumers?
