analogy of cell-cell is like chocolate factory

  1. 1. DEPARTMENT OF BIOLOGY FACULTY OF SCIENCE & MATHEMATICS INDIVIDUAL ASSIGNMENT (SBU3013) Sem II Session 2010/2011STUDENT’S NAME & ID NUMBER NOOR AZURAH ABDUL RAZAK (D20101037502)LECTURER DR. ROSMILAH MISNANTITLE CELL ANALOGYDATE / DAY 12 APRIL 2011 0
  2. 2. CELL IS LIKE A CHOCOLATE FACTORY1. Nucleus is the central office  Manage all the activities, initiates production and control activities of the factory  Nucleus coordinate the cell’s activities  It also stores genetic information of the cell2. Nucleolus is the factory employers  The employer’s place is inside the central office  Nucleolus is a dense region in the nucleus where subunits of ribosomes are assembled from protein and RNA3. Plasma membrane is the front door  Allow for things to enter and leave the factory  Is the boundary that separates the living cell from its nonliving surrounding  In cell, plasma membrane is the organelle which control of substances moving into and out of the cell4. Cell wall is the fence around the factory  The fence is built for safety purpose. It can prevent the avoiders from entering the cell  The cell wall in the cell will give protection and structural support of the cell5. Cytoplasm is the workers  Workers is the people works in the Chocolate’s Factory  Cytoplasm is inside the cell which the site for all metabolism of the cell occur6. Endoplasmic Reticulum (ER) is the stairs  Workers moving through the stairs  The Rough ER is important in the synthesis of protein  The Smooth ER is important in the synthesis of lipids, metabolism of carbohydrates and detoxification of drugs and poison 1
  3. 3. 7. Ribosome is the manager  He/she decide what characteristics the factory need and instruct the workers what they should be doing  In cell, ribosomes are produced in the nucleolus  It will produce protein by assembling amino acids according to instruction from RNA  It will control the sequence of amino acid residues in the protein formed  Ribosome in cell is the site of protein synthesis8. Mitochondria is the generator of the factory  The generator produce energy for the machines in the factory  In cell, mitochondria is the sites for cellular respiration  It will form produce energy in the form of ATP9. Vacuole is the store of the factory  The storage rooms store the all ingredients of the chocolate and give it to the workers when needed  The vacuole in cell functions to store food substances like sugars, amino acids and mineral ions  It also produce turgor pressure against cell wall for support10. Chloroplast is the canteen  Canteen is the site of food production for people in the factory  Chloroplast in the cell is the site of photosynthesis  The chlorophyll in the chloroplast function to trap sunlight energy and carry out production of ATP and NADPH11. Golgi body is the shipping area  The shipping area will pack products for distribution  Golgi body receives vesicles from endoplasmic reticulum(ER), stores, modifies the proteins and finish the polypeptides and lipids  It will carry the packages finished products in vesicles to the plasma membrane or to lysosomes 2
  4. 4. 12. Secretory vesicles is the cleaners  It is the vesicles budding from Golgi Apparatus  Secretory vesicles transport finished product to the plasma membrane  The product then released by exocytosis13. Lysosome is like the recycle bins  The recycle bins will break down and recycle used part  In cell, lysosome is the vesicle that buds from the Golgi Apparatus  It is involved in intracellular digestion14. Peroxisome is the machine  Peroxisome is the sac of enzyme  It breaks down fatty acid and amino acid15. Centriole is the trucks  Move the factory when it needs to relocate  In cell, centriole act as organizer of the spindle fibres and are involved in the separation of the chromosomes or chromatids during cell division  It also organize the formation of cilia and flagella to help in movement of the cell organelles16. Cytoskeleton is the bricks and steel  Construction materials that keep the factory from collapse  In cell, cytoskeleton has three components :microtubules, microfilaments and intermediate filaments  Cytoskeleton gives mechanical support, maintains the shape of a cell aids cell motility 3
