  1. CHARACTERISTICS of LIFE JRMG 2009

  2. Made up of cells • lowest structural level • unicellular or multicellular • prokaryotic or eukaryotic • plant or animal

  3. Based on Genetic code • what is DNA? • Units of inheritance • Double stranded • With four nucleotides • (Guanine, Adenine, Thymine, Cytosine)

  4. Reproduce • Proliferation of species • Asexual vs. Sexual reproduction

  5. Grow and Develop

  6. Obtain and use materials for energy • Metabolism Types • Anabolism • Involves putting together • Simpler to complex substance • PHOTOSYNTHESIS • Catabolism • Complex to simple substances • Release of energy • DIGESTION

  7. Response to the environment • Stimulus • anything in the environment that causes an organism to react • Light, Temperature, Odor , Sound, Gravity, Heat , Pressure

  8. Maintain internal balance • Homeostasis • process by which organisms respond to stimuli in ways that keep conditions in their body suitable for life

  9. EVOLVE

  10. EVOLUTION
