Document Summary

Microbes and microorganisms include organisms that are to small to be seen under a microscope six groups of microorganisms. Bacteria and archaea (prokaryotes) they lack nuclei meaning no membrane surrounding their gene. They are smaller than eukaryotes, grow in singles, pairs or in clusters and chains (wherever there is enough moisture. Fungi (ex. mold or yeast)(eukaryotic)- inside the cell there is genetic information contained within a membrane. They obtain food from other organisms unlike plants. Molds, typically multicellular, grow in long filaments that intertwine to make up the body, reproduce by sexual and asexual spores, produce without fusing ex cottony growth on cheese bread and penicillium chrysogenum- mold that produces penicillin. Protozoa ( first animal single celled eukaryotes similar in nutrition needs and cell structure as animals but have own category. Capable of locomotion cilia, flagella, pseudopodia- flow in the extension of direction, typically live in water, some in hosts causing disease, most asexually but some sexually.
