Plant Cell~
Show Answers:

  1. Cell Wall
    to protect the cell, providing support for upright stems (many of them) and to prevent bacteria from invading the cell
  2. Middle lamella
    Glues the cell wall of neighbouring plant cells together
  3. Nucleus
    to control all cell activities (through DNA trascription + translation) and cell reproduction (DNA replication)
  4. Nucleolus
    to make RNA and ribosomes (DNA and RNA)
  5. Nuclear envelop/membrane
    to help maintain the shape of the nucleaus and use its pores to regulate movement of molecules
  6. Nuclear pores
    to admit/release only small, select molecules and allows in RNA (messenger RNA) to leave the nucleus
  7. Chromatin
    to make the chromosomes in eukaryotic cells
  8. Mitocondrion
    to make ATP (energy) using glucose and oxygen, responsible fore cellular respiration
  9. Equation for Mitocondrion
    Glucose+Oxygen-->Water+Carbon Dioxide+Energy (ATP)

    C6H12O6+6O2-->6H2O+6CO2+38ATP(Adenosine Triphosphate)
  10. Chloroplast
    To make chemical energy from sunlight; responsible for photosynthesis
  11. Equation for Chloroplast
    Sunlight+Water+Carbon Dioxide-->Glucose+Oxygen

  12. Golgi Apparatus (G.A)
    The warehouse of the cell: modifies and sorts the product (eg: raw enzymes) made by the ribosomes; packages more complex products into Golgi vesicles to be sent to either parts of the cell of to the cell membrane to be secreted
  13. Plasmodesma
    to help control movement of water across two plants
  14. Cell membrane
    to help contol movement of molecules in and our of cell and to give shape to the cell contents
  15. Ribosomes
    to make proteins to be used inside the cell and to give shape to the cell contents
  16. Rought endoplasmic reticulum (ribbon) (ER)
    like an inner highway within the cell; binds the ribosomes to make raw proteins. To proteins are transported alond the ER to the vesicles. The vesicles take the protein either to the cell membrane or the GA for modifying or export
  17. Membrane or vacuole
    to contol the movement of molecules in and out of the vacuole
  18. Vacuole
    to store excess food or water or wastes when the need is required, when full of water, the cell maintains its shape (as opposed to wilting). Generally, there are no lysosomes in plant cells
  19. Cytoplasm
    • aka: cell liquids
    • To contain cell contents to keep them moist abd allow movement of cell paricles
  20. Chloroplast membrane/envelop
    to protect the chloroplast stacks of chlorophyll, usually a green pigment used for photosynthesis
  21. Smooth endoplasmic reticulum
    • to make lipids (fats) and fat-soluble hormones
    • NOTE: examples of plant cell oils: peanut oil, olive oil, sunflower oil
