Organisms & Atoms

  1. 1. Organisms By: Michaela Sabas Miyuki Miyamori
  2. 2. What are organisms? <ul><li>In biology, organisms is a living thing. </li></ul><ul><li>All organisms are capable of response to stimuli reproduction, growth, and development, and maintenance of homeostasis as a stable whole. </li></ul><ul><li>Viruses are not typically considered to be an organism because they are incapable of “independent” reproduction or metabolism. </li></ul><ul><li>An organism’s life span is one of the basic parameter. Some organisms can live as short as one day while others, like plants, can live up to a thousand years. </li></ul><ul><li>Organisms are semi-closed chemical systems. </li></ul>
  3. 4. Organisms bred for specific characteristics <ul><li>All members of the species sapiens are in theory, genetically able to interbred. </li></ul><ul><li>Several species may belong to a genus but the members of different species within a genus are unable to interbred, produce fertile offspring. </li></ul><ul><li>Homo has one surviving species, sapiens. </li></ul>
  4. 5. Some characteristics of an organism are the result of a combination of interaction with the environment and genetic information <ul><li>Organisms are complex system of chemical compounds, which through interaction with each other and the environment, plays a wide variety of roles. </li></ul><ul><li>They are individual units of life but they are not closed to the environment around them. </li></ul><ul><li>To operate, they constantly take in and release energy. </li></ul><ul><li>Autotrophy produces usable energy in the form of organic compounds using light form the sun or inorganic compounds while heterotrophy take in organic compounds from the environment. </li></ul><ul><li>Primary chemical element in these compounds is carbon. </li></ul>
  5. 6. Innate vs.. learned behaviors <ul><li>Innate behaviors - behavior determined by the “hard-wiring” of the nervous system. Inflexible, a given stimulus triggers a response. </li></ul><ul><li>Learned behavior - behavior that is more or less permanently altered as a result of the experience of the individual organism. For example: learning to play baseball well. </li></ul><ul><ul><li>Tax reflexes: when you touch a hot object, you quickly pull your hand away using the withdrawal reflex. </li></ul></ul><ul><ul><li>Instincts: complex behavior patterns which, the reflexes are inborn. Rather inflexible and valuable at adapting the animal to its environment. </li></ul></ul>
  6. 7. Organisms are composed of cells, which are the fundamental units of life <ul><li>All existing organisms share certain traits including cellular structure and genetic codes. </li></ul><ul><li>scientist interpret this to mean that all existing organisms share a common ancestor which had already developed the most fundamental cellular processes. But these is no sciencetific consensus on the relationship of the three domains of life: Archaea, Bacteria, and Eukaryota (or the organs of life). </li></ul>
  7. 8. Unicellular vs.. multicellular <ul><li>Organisms are either unicellular or multicellular not both. </li></ul><ul><li>Unicellular - single celled or to be composed of as in human, many billions of cells grouped into specialized tissues and organs. Can survive without the help of other cells. </li></ul><ul><li>Multicellular - many celled, described any organisms made up of more than one cell. </li></ul>
  8. 9. Bibliography <ul><li>http://courses.coe.asu.edu/dbclark/teams/pond/Pond%20Detective%20(intro.vocab).htm </li></ul><ul><li>http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/I/InnateBehavior.html </li></ul><ul><li>http://en.wikipedia.org/wiki/Organism </li></ul>
