Transcript

  • 1. Characteristics of Living Things• Biologists have formulated a list of characteristics by which we can recognize living things
  • 2. Living Things• What are some examples of living things?-Animals Plants●What about these things?Rocks, bicycles, books
  • 3. All living things share some basic properties.Cellular OrganizationReproductionMetabolism (Obtain and Use Energy)HomeostasisHeredityResponsivenessGrowth and DevelopmentAdapt Through Evolution
  • 4. Cells are basic structural units of life. Smallest unit capable of all life functions.Cells are the building blocks of all organisms = living things. Two types of cells are:Unicellular Organisms Multicellular Organisms The organism is made up of Entire organism is made many cells up of one single cell Cells have specialized Bacteria and protists functions within the organism
  • 5. C ells
  • 6. iC e llu la r
  • 7. lt iC e llu la r
  • 8. Reproduction is the process of producing new organismsof the same type. Two types of reproductionAsexual Reproduction Sexual Reproduction Two different parentA single parent organisms contribute geneticorganism reproducing by informationitself Involves the combination of male and female sex cells
  • 9. As e xua l
  • 10. S e x u a l: a n e wg e n e t icc o m b in a t io n
  • 11. Living organisms need energy to grow,develop, repair damage, and reproduce
  • 12. AnabolismThe process of building up complex substancesfrom simpler substances  Building up cells and cellular components  Photosynthesis
  • 13. CatabolismThe process of breaking down complexsubstances into simpler substances to releaseenergy Digestion Cellular Respiration
  • 14. MetabolismThe total of all chemical reactions inan organism Anabolism + Catabolism = Metabolism
  • 15. A stable state of conditions in the bodythat are necessary for lifeBody temperatureBlood volumepH balanceWater balance
  • 16. S t a b leIn t e r ior
  • 17. E v e n t h o u g h e x t e r io rc o n d it io n s a r e c h a n g in g
  • 18. Genes carry hereditary informationGenes are composed of DNAHeredity is the reason children resemble their parents Mutations change DNA code and can be passed from generation to generation
  • 19. An example is a plant’sOrganisms react to stimuli: leaves and stems growingLight toward lightTemperatureOdorSoundGravityHeatWaterPressure
  • 20. Growth means to get bigger in size
  • 21. Development involves a change in thephysical form or physiological make-up ofan organism- An example would be how a frog is conceived and born.- A frog begins as a single cell in a fertilized egg and then grows into a tadpole and eventually into a fully grown frog.
  • 22. D e v e lo p m e n t
  • 23. AdaptationA process that enablesorganisms to become bettersuited to their environment Species obtain adaptationsthrough evolution over greatperiods of time
  • 24. An Example of AdaptationDesert plants have succulent waxy leaves andstems to store water and reduce water loss
  • 25. Living things adapt and evolve
