CHACTERISTIC OF LIFE

Cards (26)

  • Life
    A high degree if order
  • Biological organization
    Based in a hierarchy of structural levels
  • Biological organization
    Atom - Molecule - Macromolecule - cell - tissue - organ - organ system - organism - population - community - ecosystem - biosphere
  • Atom
    The lowest level that are ordered into complex biological molecules
  • Organelles
    Many molecules that are arrange into minute structure and which are the components of cells
  • Cells
    The subunits of organisms, the units of life
  • Multicellular
    Exhibiting three major structural levels above the cell; tissue, organ, organ system.
  • Population
    Localized groups of organisms belonging to the same species
  • Community
    Population of several species in the same area
  • Metabolism
    The process of getting energy from nutrient molecules of food and using it to maintain the structure and function of a cell
  • Anabolism
    Is called the structure or building up phase
  • Anabolism
    Building up protoplasm from simple compounds and elements which are product of digestion
  • Catabolism
    The destructive or breaking down phase
  • Ecosystem  

    The population interacts with their physical environment
  • Homeostasis
    The maintenance of a stable level of internal conditions
  • Reproduction
    Living things become capab of perpetuating their own kind
  • Reproduction
    It can be asexual or sexual
  • Asexual
    Only a single parent is needed
  • Sexual
    Requires two parents; involves gametes or sex cell
  • The ability of living things to respond often results in movement
  • Adaptation
    Special characteristics that enable plants and animals to be successful in a particular environment
  • Adaptation
    Afford the organisms a better chance to survive
  • Problem
    Identifying or defining a problem
  • Hypothesis
    Accumulating data and formulating tentative hypothesis
  • Experiment
    Testing hypothesis
  • Conclusion
    The outcome result of the tested data
