Title: Levels of Organization


1
Levels of Organization
2
  • ATOMS
  • Smallest part of matter
  • NON-living
  • Make up elements

3
  • Molecules
  • 2 or more bonded atoms
  • Form compounds
  • NON-living

4
  • Macromolecule
  • Very large molecules
  • Proteins, fats, carbohydrates, nucleic acids
    (DNA)
  • NON-living

5
  • Organelles
  • Tiny organs of cells
  • Made of macromolecules
  • Cannot live on their own

6
  • Cell
  • Made of organelles
  • Basic unit of structure function
  • LIVING

7
  • Tissue
  • The same kind of cells working together to
    perform a function digestion, communication,
    support, cushioning, etc.
  • Living

8
  • Organs
  • Tissues that work together
  • Living
  • Heart
  • Liver
  • Brain

9
  • Systems
  • Organs that work together
  • Living
  • Digestive
  • Nervous
  • Excretory
  • Respiratory
  • Circulatory

10
  • Organism
  • Entire living things (organisms)
  • Usually made of systems
  • May be a single cell
  • Organelles no tissues or systems
  • Living

11
  • Population
  • Same type of organism living together same
    species

12
  • Community
  • Several populations living together
  • Population interact

13
  • Ecosystem
  • A biotic (living) community plus the abiotic
    (nonliving) features

14
  • Biome
  • Similar ecosystems on earth together

15
  • Biosphere
  • Whole living layer around the globe
  • Includes abiotic features
