The document is an individual assignment comparing the structures and functions of a cell to that of a chocolate factory. It lists 16 analogies: (1) The nucleus is the central office that manages all activities; (2) The nucleolus are the factory employers that assemble ribosomal subunits; (3) The plasma membrane is the front door that controls what enters and exits the cell.

2. CELL IS LIKE A CHOCOLATE FACTORY
1. 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 cell
2. 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 RNA
3. 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 cell
4. 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 cell
5. 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 occur
6. 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

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 synthesis
8. 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 ATP
9. 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 support
10. 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 NADPH
11. 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

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 exocytosis
13. 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 digestion
14. Peroxisome is the machine
 Peroxisome is the sac of enzyme
 It breaks down fatty acid and amino acid
15. 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 organelles
16. 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
