  • cell wall function is that it contains cellulose structural support cell
  • cell membrane controls entry an exit of substances
  • cytoplasm is site of most reactions
  • nucleas contains genetic information and controls activites of cells
  • mitochondrian is for aerobic respiration
  • chloroplast is for photosynthesis
  • vacuole contains water sap and helps make cell firm
  • tissues are groups of similar cells with similar function
  • organs consist of several tissues performing specific functions
  • organ systems consist of a number of organs working together to perform an overall function
  • flaccid is when a plant has lost water but the cell membrane has not peeled away. It will lose its firmness and wilt
  • plasmoysis is when the plant cell has lost lots of water and the membrane HAS peeled away
  • Turgid is when the plant has lots of water and the cell is firm. The vacuole pushes against the cell wall
  • Osmosis
    Movement of water molecules from high to low concentration down the conc. gradient through a selectively permeable membrane
  • Passive Transport

    Movement of molecules from high to low concentration without using energy
  • Diffusion
    Random movement of molecules from high to low concentration down the conc. gradient until they are evenly distributed
  • A plant cell contains ..
    vacuole, nucleus, mitochondria, chloroplast, cytoplasm, cell membrane, cell wall
    A) cell membrane
    B) vacuole
    C) chloroplast
    D) cell wall
    E) nucleus
    F) mitochondria
    G) cytoplasm
  • A animal cell contains..
    nucleus, cytoplasm, mitochondria, cell membrane
    A) cytoplasm
    B) cell membrane
    C) mitochondria
    D) nucleus
  • Osmosis and Diffusion are both passive processes meaning they do not need energy to occur but Active transport needs the ATP produced from respiration
  • Visking tubing
    can be used as a model for the small intestine
