    CTO3.ppt CTO3.ppt Presentation Transcript

    • LEVELS OF ORGANIZATION
      • CTO 3
    • Cells The basic structure of living things Human body contains about 100 trillion cells
    • UNI CELLULAR ORGANISMS
      • CELL = ORGANISM
      • No levels
      • Each type of cell is different organism.
    • MULTI CELLULAR ORGANISMS
      • Cells - Tissue - Organ - System - Organism
      • Different types of cells are needed to create different levels.
    • SPECIALIZATION
      • In MultiCellular organisms, Cells differ from one another for different jobs.
      • In UniCellualr organisms- only one cell.
    •  
    • TISSUE
      • GROUP OF SAME CELLS
      • 4 MAIN TYPES:
        • CONNECTIVE
        • MUSCLE
        • NERVOUS
        • EPITHELIAL
    • TISSUE
      • CONNECTIVE
      • Connects other tissues together.
      • ie: Fat, cartilage, bones, blood, ligaments and tendons.
      • EPITHELIAL
      • Covers the surface of your body and lines the inside of organs.
    • TISSUE
      • MUSCLE
      • Movement of the body’s functions.
      • ie: voluntary & involuntary.
      • NERVOUS
      • Controls & coordinates all body functions.
      • ie: brain, nerves
    • 4 KINDS of TISSUE
      • (group of same cells)
    • WHAT TYPE OF TISSUE?
    • ORGAN
      • Different tissue types working together with specific job.
      • ie: stomach
    • ORGANS (group of diff. tissues)
    • ORGAN SYSTEMS
      • A group of organs and parts that work together to perform a specific job.
    • SYSTEMS ( group of diff. Organs)
    • Integumentary system
    • SKELETAL SYSTEM
    • MUSCU-LAR SYSTEM
    • RESPIRATORY SYSTEM
    • CIRCULATORY SYSTEM
    • All together =
      • ORGANISM
    • ORGANISM
      • Multi-cellular Organisms: Single living unit composed of different systems working together. CTO 3
      • Uni-cellular Organisms: Single living unit composed of a single cell. C = O
    •  
    • Remember:
      • ORGANISM POPULATION
      • COMMUNITY ECOSYSTEM
