CHARACTERISTICS OF LIFE

• • Living things(biotic)
• Non-Living things(abiotic)
• Order

  • Life began from a single cell.
• CHARACTERISTICS OF LIFE

  1. ORDER
  2. ADAPTATION
  3. METABOLISM
  4. REGULATION
  5. RESPONSIVENESS
  6. REPRODUCTION
  7. GROWTH AND DEVELOPMENT
  8. EVOLUTION
  9. GENES
• Levels of Organization

  • molecule→cells→tissues→organs→organ system→organism→population→community→ ecosystem→biodiversity
• Taxonomy/Structures

  • Living things have order and are arranged into groups
• Domain → Kingdom → Phylum → Class → Order → Family → Genus → Species
• Carl Von Linnaeus

  • Father  of Taxonomy, Swedish botanist
  • His first classification guide Systema Nature(1735) 

  Introduced the  binomial nomenclature(genus and species)

  • two latin words to describe an organism
• • International Code of Botanomical Nomenclature(ICBN)
• • International Code of Zoological Nomenclature(ICZN)
• Binomial nomenclature  rules for writing the scientific names of organisms
•  Adaptation

  • “Coboy” Ability to adjust,adapt, survive to environmental changes 
  • The fitness or species will determine its fate of survival
• Metabolism

  • Intake of nutrients needed by an organism to survive.
• Autotrophs(Producers)- organisms that produce their own food using environmental energy sources.
• • Heterotrophs(Consumers)- organisms that obtain energy by consuming other organisms
• Structural Adaptation

  • Physical or structure of an organism. How physical their physical aspects help them adapt and survive in their environment
• Physiological Adaptation

  • Body composition (toxins, poison, virus), chemical substances developed in the body.
• Behavorial Adaptation

  Courtship and mating
• Natural Selection- organisms with better traits for their environment are more likely to survive and reproduce, passing it to their offspring
• Speciation- the emergence of new, distinct species changes in genetic material via mutations, gene flow, genetic drift, and natural selection
• Regulation

  Is a way of how an organism copes up to its environment to maintain homeostasis inside the body
•  Responsiveness

  The ability to react and respond to environment stimuli
• Reproduction

  • The ability of an organism to reproduce and pass their genetic information to its offspring
• Asexual- one parent (microorganism), identical to the parent cell
• Sexual- two parent, complex organisms
•  Growth and development

  Increasing in size until they become an adult
