 Any of various submicroscopic agents that infect living organisms, often causing disease, and that consist of a single or double strand of RNA or DNA surrounded by a protein coat. Unable to replicate without a host cell, viruses are typically not considered living organisms. ]]> 2016-12-19 15:07:39 UTC https://padlet.com/1717833/rks8kclnt1q3/wish/144322875 1717833 https://padlet.com/1717833/rks8kclnt1q3/wish/144323703 Definition
 Bacteria are microscopic living organisms, usually one-celled, that can be found everywhere. They can be dangerous, such as when they cause infection, or beneficial, as in the process of fermentation  and that of decomposition.]]> 2016-12-19 15:11:10 UTC https://padlet.com/1717833/rks8kclnt1q3/wish/144323703 1717833 https://padlet.com/1717833/rks8kclnt1q3/wish/144324259 any of a large division of thallophytes, including molds, mildews, mushrooms, rusts, and smuts, that are parasites on living organisms or that feed upon dead organic material: fungi lack chlorophyll, true roots, stems, and leaves, and reproduce by means of spores]]> 2016-12-19 15:13:35 UTC https://padlet.com/1717833/rks8kclnt1q3/wish/144324259 1717833 https://padlet.com/1717833/rks8kclnt1q3/wish/144327209 In biology parasitism is a non-mutual symbiotic relationship between species, where one species, the parasite, benefits at the expense of the other, the host.

Some parasites only replicate within a host organism, but some can multiply freely in the environment. Parasites can be made of one cell, as in the case of Giardia, or many cells, as with parasitic worms]]> 2016-12-20 15:09:48 UTC https://padlet.com/1717833/rks8kclnt1q3/wish/144473273 1717833 https://padlet.com/1717833/rks8kclnt1q3/wish/144473588 A virus is made up of a core of genetic material, either DNA or RNA, surrounded by a protective coat called a capsid which is made up of protein.
