Divison of Labor

• A cell is made up of many parts with different functions that work together. Similarly, the parts of a factory or a machine work together to carry out different functions and come up with a product.

Answer the following questions.

• 1. What are some of the different parts of a computer? What are the functions of these computer parts?

• 2. How do the functions of these computer parts correspond to the functions of certain cell parts?

Cell Membrane

• Guard station—– lets somethings in– Keeps some things out

Cell Wall (plants only)

• Wall outside the factory guard gate– Protection and

strength

mitochondria

• Generator– Creates energy for the

factory

Golgi Apparatus

• Packaging, processing– Puts wrapper on the

candy bar

Nucleus

• CEO, central office– Directs the factory– Contains the recipe

Nucleolus

• Machine makers– Place where the

assembling machines (ribosomes) are made

Ribosomes

• Assembling machines– Assembles the candy

bars, takes them to packaging (golgi)

Endoplasmic reticulum

• Inner-factory transport– Conveyor belt,

transports candybars (proteins)

Lysosome

Vacuole

• Trashcans-– Contains all of the

waste

Chloroplast (plants only)

• Solar panels on the factory– Converts sunlight to

usable energy for the factory
