Disease Microbes cause disease by directly damaging tissues and weakening bodily functions or by producing toxins that do.
Pathogenic microbes the proportion of pathogenic microbes on earth is very small
Producers produce carbohydrates break down starch into sugar convert sugars into alcohol
Water Dwelling microbes algae and bacteria largest producers of carbon containing compounds through photosynthesis
Some microbes are unable to take in Carbon Dioxide from the air. They get Carbon from bicarbonate in the water
Ion an atom that carries a positive (+) or a negative (-) charge carries the charge because it has gained or lost one or more electrons
Microbes use CHOs (carbohydrates) synthesized during photosynthesis (Ps) to make cell structures and as an energy source Provide food for larger organisms Replenish Oxygen supply
Single Celled Fungi Yeasts Producers in wine making, bread baking or beer brewing. Convert sugar to alcohol in fermentation process
Cheese Making bacteria convert lactose (milk sugar) to lactic acid
Contribute to production of food and other substances by their enzymes
Enzymes organic molecules that speed up biochemical reactions without being used up or becoming part of the end product. A catalyst - causes a reaction to take place
Examples foods medicines vitamins leather processing textile production
Decomposers and Recyclers worlds greatest recyclers Keep elements like C and N cycling through the environment Used to treat sewage, clean up toxic wastes, processing materials
Recyclers more than one type of bacterium is needed to convert atmospheric N into a form useable by plants. Requires three different chemical reactions.
Production through decomposition Methane - decomposition of organic matter Methanogens - swampy areas, land fills, digestive tract of ruminants.
Production through decomposition Linen fabric is made from flax stems Stems are immersed in water Bacterium digests pectin that makes the stalks stiff
Linen Fabric Production remainder is washed dried and spun into thread and then woven into fabric
Basic features of MOs (microorganisms) 4 major groups –bacteria, fungi, protists, viruses Viruses are not made up of cells and are not considered organisms by many microbiologists.
Bacteria, fungi and protists have a cellular structure, a membrane surrounding cytoplasm
Protists have an inner compartment nucleus DNA in non circular chromosomes unicellular or multicellular protozoans, algae, others resemble fungi
Fungi have cellular structure non circular chromosomes in fungi with many cells, walls between cells are sometimes not complete cytoplasm and nuclei can stream from one cell to another within slender filaments of cells called hyphae
