Bacteria to Plants
classification, bacteria, viruses
| qustion/answer | term/definition |
|---|---|
| Classification: | grouping thing based on there simillarities |
| who's the first scientist to develop the first classification system? | Aristotle |
| taxonomy: | scientific study how living things are classified. |
| why do biologists use classification? | to organize living things into groups so that they are easier to study. |
| subgroup: | smaller groups of organisms that showed other similarity's |
| who expanded Aristotle's idea of the classification system? | Linnaeus |
| binomial nomenclature: | each organism is given a two part name. |
| what is the first and second part of an organisms scientific name? | one is the genus and the second is species. |
| genus: | a grouping that contains a similar and closely related organisms. for example puma, leopard, and cat in the felis genus. |
| species: | a group of similar organism's that can mate and produce fertile offspring in nature. it may describe a feature of an organism like where it lives. |
| what are the seven levels of classification? | kingdom, phylum, class, order, family, genus species. |
| what are the six kingdoms? | archeabacteria, Eubacteria, animal, plants, fungi, protists. |
| archeabacteria: | it means ancient bacteria. it can be autotroph or heterotroph. they are also prokaryote, unicellular. found in extreme environments. |
| prokaryote: | organisms whose cells lack a nucleus. |
| nucleus: | dense area in a cell that contains nucleic acids. |
| autotroph: | organism can make their own food |
| heterotoph: | organisms that can't make their own food. |
| eubacteria: | it;s unicellular prokaryotes. it can be autotroph or heterotroph. chemical makeup is different from archeabacteria. this is helpful for example vitamins. are not found in extreme environment. |
| protists: | are called "odds and end" because the members are different from another. it can be autotrophs and heterotrophs. both unicellular and multicellular. also they are eukaryotes. example would be seed weed. |
| eukaryotes: | organisms with the cells that contain nuclei. |
| fungi: | it can be unicellular or multicellular. its eukaryotes. it is also heterotrophs. examples are mushrooms, molds, and mildew. |
| plants: | they are all multicellular and eukaryote. they are also autotrophs. they feed most of the heterotrophs. |
| animals: | they are multicellular and eukaryotes. all of them are heterotrophs. |
| virus: | a small non living particle that invades and then reproduces in a living cell. virus can infect organisms in the six kingdoms. |
| are viruses non living or living? | non living because it doesn't use its energy to grow and it doesn't respond to it's surroundings. |
| host: | a living thing that provides a source of energy for a virus or organism. |
| parasites: | organisms that live in a host and cause harm to the host. almost all viruses are similar to this because they destroy the cells. |
| what are the two basic parts of the virus? | 1. an outer coat that protects the virus ( the coat of virus is made of proteins and the shape of the proteins allows the viruses coat to attach to certain cells in the host). 2. inner core made up of genetic material. |
| active virus: | it attaches to the surface. then it injects the genetic material. next the genetic material takes over the cells function and cells start producing proteins and genetic material. then it makes copies of itself to fill the bac |
| hidden virus: | virus attaches to the surface and it injects genetic material. soon it becomes a part of the material in the bacterium. after that the virus removes itself and becomes active. then the cells produce proteins and genetic material and makes copies of itself |
| bacteria: | its prokaryote. the genetic material in their cells is not contained in a nucleus. its also unicellular. |
| what are the three basic shapes of bacteria? | 1. spherical 2. Rodlike 3.spiral |
| what are the two kingdom of bacteria? | 1. archeabacteria 2. Eubacteria |
| asexual reproduction: | a reproductive process that involves only one parent and produces offspring that are identical to the parent. |
| Binary Fission: | a process in which one cell divides to form to identical cells. |
| sexual reproduction: | involves two parents that combine their genetic material to produce a new organism which differs from both parents. |
| conjugation: | one bacterium transfers some of it's genetic material into another bacterial cell through a thin thread like bridge that joins the two cells. |
| infectious diseases: | illness that pass from one organism to another. |
| what are four ways to spread infectious diseases? | 1. through contact of a infected person 2. a contaminated object 3. a infected animal 4. a environmental source |
| viral diseases: | no medication can cure this disease, but there are some medications that can make you feel better. |
| bacterial disease: | many bacterial diseases can be cured by a medication called antibiotics. |
| antibiotic: | a chemical that can kill bacteria without hurting a persons cell. also this is only mean't for bacterial diseases. |
| vaccine: | helps to prevent spread of many infectious diseases. it is a substance that stimulates the body to produce chemicals that destroy viruses and bacteria. |
| halitosis: | bad breath do to lack of saliva in your mouth. |
| slaiva | your spit. spit is 99% water with a splash of mucus. has chemicals that help kill bacteria. |
