7 Prokaryote and Eukaryote Cells S - Page 1 preview imageProkaryotic a n dEukaryotic CellsDo all cells have the same structure?W hAn efficiency apartment is a one-room apartment. This one room is where yousleep, eat, shower, and entertain your guests. It all happens in one room. I t is asimple way of living in a small space. A mansion is a large, complex living spacewith many separate rooms. There are rooms for cooking, eating, sleeping,bathing, reading, watching TV, entertaining guests, exercising, and storage. Therooms in a mansion are constructed for the specific things you would likeable to do. You can live in simple efficiency or complexity. Fn this activitybe looking at cells that are as simple as a one-room efficiency apart- ment or ascomplex as a mansion.M o d e l 1 - T h r e e T y p e s o f B a c t e r i a l Cellske to berwe willCell wallRibosomesCytoplasmFlagellum1 .The three bacterial shapes in Model 1 are referred to ascoccus(sphere),spirillum,andbacillus£rpd).

What is the name of the outermost layer that forms a boundary around theoutside of each cell?Cell Wall4. How is the DNA described and what does this mean?The bacteria is free floating which implies that DNA can move aroundanywhere within the cellPOGIL~ Activities for High School2

One of the bacteria in Model 1 has a tail-like structure.a. What is this structure called?Flagellumb. What might be the purpose of this structure?It helps bacteria move aroundc. Based on your answer to the previous question, what might you inferabout the absence of this structure in the other two bacteria cells?They don't move around they just stay in one place so they don'tneed flagellumM o d e l 2 - A n i m a l a n d P l a n t CellsAnimal CellPlant CellCell membraneTemporaryvacuoleNuclearmembraneD N ANucleolusNucleusChloropla s tCytoplasmEndoplasmicjeticulumRibosomes(freeo r attached)LysosomeMitochondriaVesicleGolgi apparatusLarge p e r m a n e n tvacuo leCell wall7.
