Zoology Notes: General Properties of Living Things 1. Chemical Uniqueness - Living systems demonstrate a unique and complex molecular organization. - Macromolecule - complex, large molecules that make up living things: The four macromolecules of living things are Lipids, carbohydrates, proteins and nucleic acids 2. C omplexity and Hierarchical Organization - Living systems demonstrate a unique and complex hierarchical organization -Hierarchy Levels include macromolecules, cells, organisms, populations, species 3. Reproduction - Living systems can reproduce themselves 4. P ossession of a Genetic Program - a genetic program provides fidelity of inheritance -For animals and other organisms, DNA stores the genetic information - DNA is a very long, linear chain of subunits called nucleotides each one contains a sugar, a phosphate and a nitrogen base. 5. M etabolism - a group of processes that includes digestion, recovery of energy(respiration) and synthesis of molecules and structures by organisms. -Physiology - The study of metabolic functions from the biochemical to the organismal level 6. Development - All organisms pass through a characteristic life cycle -Metamorphosis - sharp change in form that happens during the development of an organism 7. Environmental Interaction - All animals interact with their environments which is known as Ecology. - Irritability - a general property of all organisms involving the ability to respond to stimuli or changes in the environment 8. M ovement - Living systems and their parts show precise and controlled movements arising from within the system
