Cell City Introduction!Floot ing oround in the cytop losm ore smol l

structures colled organelles. Like the orgons in yourown body , eoch one corr ies out o specif ic funct ionnecessory f or the cef l to survive.

Imogine the cell os o minioture city. The orgonelles might represent componies, plocesor ports of the city becouse they eachhave similor jobs. Below arethe descriptions ofimportont ports of the Cell City.

A. City Limits - control whot goes in ond out of the city

B. Rood System - Allows for movement throughout the city.

C. City Holl - Controls oll the octivities of the city.

D. City Auditor - Stores oll the records of the city ond posses them on os the city grows.

E. City Plonning Office - A place in the city holl where plons ore mode f or theconstruction of the city.

F. Construction Compony - Builds structuresfor the city.

G. Delivery Von - delivers products mode at the construction compony to other locotionsin the ci ty.

H. Food Processing Plont - Processes lorge guontities of food entering the city intosmoller pockoges thot con be used more eosily.

I. Worehouse - Stores moteriols needed by the city.

J. Power Compony - Produces ene?gy for the city.

K. Solor Power Plont - Uses the sun's energy to produc e power for the city.

As you move through this worksheet, see if you con motch the important ports of thecity f isted obove to the specif ic orgonelles found in celfs. Be sure to write neotly, qnd incompfete sentences.

1. The nucleus is o large, round/ovol structure usuolly locoted neor the center of the cell.It is the confrol center for oll the octivities of the cell. i) Whot compony or ploce doesthe nucleus resemble in o Cell City? ii)Why do you think so?

Z. The cell membrone is o thin, f lexible envelope thot surrounds the cell. ft ollows the

cell to chonge shope ond controls whot goes into ond out of the cell. i) Whot comPony

or ploce does the cell membrane resernble in o Cell City? ii)Why do you think so?

3. The endoplosmic reticulum consists of o network of tube-like Possogewoys thot

proteins from the ribosomes ore tronsported through. i) Whot comPony or ploce does

the endoplosmic reticulum resemble in o Cell City? ii)Why do you think so?

4" The ribosomes ore smoll groin-like bodies mode mostly of RNA ond produced in the

nucleolus. Proteins ore constructed of the nibosomes. i) Whot comPony or ploce do the

ribosomes resemble in o Cell City? ii)Why do you think so?
