Lab 4: Fungi Non-filamentous forms — Single-celled Yeasts Do an Internet search for a microscopic image of baker’s yeast‚ Saccharomyces cerevisiae (Ascomycota). Answer the following questions: 1. Do the yeast cells have a definite shape or is there considerable variation? Yeast cells seem to vary in shape‚ some look to be more oval and round‚ although. some slides did show pear and cylinder shapes. 2. Can you detect any subcellular structure? I cannot detect a clearly visible

Compare the Rate of Carbon Dioxide Production by Yeast under Anaerobic Conditions using different Carbohydrate Substrates. Hypothesis. The hypothesis that I draw is that "" out the five carbohydrate substrates that I will use‚ Glucose will produce the highest volume of Carbon Dioxide at every five-minute interval. Null Hypothesis. The null hypothesis that I am composing is that "" the five carbohydrate substrates that I am to use will not produce any Carbon Dioxide. Scientific Research. Under anaerobic

biodegradable wastes (Cayetano‚ 2008;www.senatorpiacayetano.com/psc/pressreleasedetails.php?recordID=175) Biodegradable plastics are degradable plastics on which the degradation results from the action of naturally occurring micro-organisms such as bacteria‚ fungi ‚ and algae (info@epi-global.com). These plastics are broken down into water‚ carbon dioxide‚ methane and biomass primarily through enzymatic action on microorganisms(Azios‚ 2007www.csmonitor.com/2007/1219/p16s01 -sten.html).

differentiate between bacteria‚ fungi and yeast‚ we plant four different microbes in plates under the same environment for one week and compare the growth of the four microbes by macroscopic and microscopic observation. Meanwhile‚ the diversity of bacteria and fungi in humans‚ the environment and wood could be observed. In addition‚ the four substrates are cultured in two media‚ MEA and NA‚ under the same condition. Thus‚ how nutrients affect the growth of bacteria and fungi could be achieved. During the

Same‚ Same But Different by Jenny Sue Kostecki-Shaw The book that I chose for this assignment is Same‚ Same But Different by Jenny Sue Kostecki-Shaw. At first‚ I thought it would be very difficult to find a book that was suitable for my presentation and it was not until I went to my school practicum that I found one. The theme for the week was rainbows‚ colours and diversity and to help children understand more about the different cultures around the world‚ my mentor teacher read Kostecki-Shaw’s

A fungus (/ˈfʌŋɡəs/; plural: fungi[3] or funguses[4]) is a member of a large group of eukaryoticorganisms that includes microorganisms such as yeasts and molds (British English: moulds)‚ as well as the more familiar mushrooms. These organisms are classified as a kingdom‚ Fungi‚ which is separate from plants‚ animals‚ protists and bacteria. One major difference is that fungal cells have cell walls that contain chitin‚ unlike the cell walls of plants and some protists‚ which contain cellulose‚ and

and the reproductive cycle with flowering and pollination is completed under water. Seagrasses have a number of adaptations to the submerged life form (Borum et al‚ 2004). Thalassia hemprichii is common on mud-coral-sand or coarse coral-sand substrates‚ in sheltered habitats in the Philippines. The plant has been observed growing from the base and through fingers of corals at 6 m deep. T. hemprichii may be found mixed with Syringodium isoetifolium‚ Cymodocea serrulata‚ C. rotundata‚ Enhalus acoroides

a good report on fungus - The kingdom of Fungi contains single-celled and multicellular organisms that absorb nutrients for food. Fungi‚ together with bacteria decay and decompose organic matter. Some fungi can be parasitic and cause serious diseases in plants and animals. Though considered an individual kingdom today‚ traditionally fungi were classified as plants with no stems‚ leaves‚ or chlorophyll. About 100‚000 species of fungi are known. Most fungi are made of protoplasm-containing tubes called

such as fructose. The enzyme helps a chemical reaction take place quickly so that the reaction happens properly. In order for that to happen the enzymes process by the lock and key model‚ the lock is the substrate and the enzyme is the key. The active sites are specific to a certain substrate of a molecule‚ so the enzymes only have one job to do. The shape of an enzyme is not changed or consumed during these reactions. However‚ without enzymes the reactions would take too long and would not breakdown

EFFECT OF BIODEGRADABLE SM PLASTIC BAG IN DIFFERENT SUBSTRATE ABSTRACT The purpose of this Investigatory project is to determine the effect of different substrates on the biodegradability of SM plastic bags. The materials needed are: 6‚ 1-litre glass jars; 6‚ 7”x9” aluminums trays; 12 pcs. 3”x4” SM plastic bags; 500g loam soil; 500g compost soil; 500mL seawater; 500mL tap water; Analytical balance; Graduated cylinder; and Weighing scale. The procedure involved cutting the SM plastics bags
