The flashcards below were created by user ellewrigley on FreezingBlue Flashcards. What would you like to do?


  1. Cell wall
    • Most commonly found in plant cells
    • protection, support and shape
  2. cell membrane
    • lets some things in and/or out of the cell
    • acts as a boundary layer to contain the cytoplasm (fluid in cell)
  3. Endoplasmic Reticulum
    • Structure - sheets of unit membrane with ribosomes on the outside
    • - forms a tubular network throughout the cell
    • Function - transports chemicals between cells and within cells
    • - provides a large surface area for the organization of chemical reactions and synthesis
  4. Vacuole
    • - produces turgor pressure against cell wall for support
    • - stores water and various chemicals
    • - may store insoluble wastes
  5. Lysosome
    digests materials
  6. Mitochondrion
    • INside are folded membrane which provides a larger surface area where enzymes for respiration are attached.
    • site of cellular respiration ie. the release of chemical energy from food
    • Glucose + Oxygen ------> Carbon Dioxide + Water + Energy
  7. Golgi Apparatus
    Chemically modifies, stores and distributes substances made by the endoplasmic reticulum
  8. Chloroplast
    site of photosynthesis

    chlorophyll Carbon Dioxide + Water ---------------> Glucose + Oxygen radiant energy (food)
