Transcript

  • 1. THE ORGANIZATION OF LIVING THINGS
  • 2. BENEFITS OF BEING MULTICELLULAR • Larger Size: larger organisms are prey for fewer predators. Also, large predators can eat a wider variety of prey • Longer Life: not limited to the life span of any single cell • Specialization: each type of cell has a particular job. This makes the organism more efficient!
  • 3. EXAMPLE: Cardiac Muscle Cell
  • 4. • Level 1: Cell • -smallest unit that can perform life processes independently • -vary in size and shape • -Example: plant cell (square) and animal cell (round)
  • 5. LEVEL 2: TISSUE CELLS WORKING TOGETHER • Tissue: a group of cells that work together to perform a specific job Animals have 4 basic types of tissues: 1. nerve tissue
  • 6. 2. muscle tissue 3. connective tissue
  • 7. 4. Protective Tissue Example: Adipose (fat) cells in the skin
  • 8. PLANT TISSUES • Plants have 3 types of tissue: 1. transport tissue 2. protective tissue (dermal) 3. ground tissue
  • 9. LEVEL 3: ORGAN TISSUES WORKING TOGETHER • Organ = a collection of tissues that carry out a specialized function of the body • Example: heart - has mostly cardiac tissue, but also has nerve tissue and tissues of the blood vessels that all work together • Other examples: stomach, intestines, brain, and lungs
  • 10. • Examples in plants: the leaf plant organ that contains tissue that traps light energy to make food • Also: stems and roots
  • 11. IS THAT A FACT?! In your lifetime, your body will shed about 40 pounds of dead skin!
  • 12. LEVEL 4: ORGAN SYSTEM ORGANS WORKING TOGETHER • Organ system = group of organs that work together to perform body functions • Examples: digestive system, which includes several organs, such as the stomach and intestines
  • 13. ON ITS OWN: ORGANISM • Organism = a living thing; anything that can carry out life processes independently • An organism can be unicellular, like this bacteria:
  • 14. • OR an organism can be multicellular, like you!
  • 15. STRUCTURE & FUNCTION • In organisms, structure and function are related. Structure = arrangement of parts in an organization -Includes the shape of a part and the material of which the part is made Function = the job that the part does
  • 16. EXAMPLE OF STRUCTURE AND FUNCTION: The structure of the lungs is a large, spongy sac. Blood vessels wrap around aveoli (air sacs). The structure of the aveoli and blood vessels enable them to perform a function, which is bring oxygen into the body and take out carbon dioxide.
