TITLE CELL ANALOGY

DATE / DAY 12 APRIL 2011

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

1

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

2

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
