In general, how are prokaryotic and eukaryotic cells different and how are they similar? AN Both mitochondria and chloroplasts contain DNA, RNA, and ribosomes that resemble those found in SW bacteria. In prokaryotic cells, the genetic material is found in a central region called the nucleoid, while in ER eukaryotic cells, it is contained in the membrane-bound nucleus. Also, eukaryotic cells contain membrane : systems that form organelles, while prokaryotic cells do not. A plasma membrane surrounds both prokaryotic and eukaryotic cells. 92. If prokaryotic cells do not have mitochondria, where do they produce their cellular energy? ANSWER: The plasma membrane contains most of the molecular systems needed to metabolize food molecules to ATP. 93. Compare animal and plant cells. How are they different? How are they the same? ANS Both animal cells and plant cells have a plasma membrane, nucleus, mitochondria, endoplasmic reticulum, WER ribosomes, and Golgi complex. Animal cells, however, do not have a cell wall, central vacuole, or : chloroplasts. 94. Explain how a cell isolated from the pancreas would be the same as a muscle cell. How would the two cell types be different? AN Both cell types would contain the same organelles; however, due to the very different functions of the two SW cells, the proportion of certain organelles would be different. For example, the pancreatic cell, which is ER involved in the production of digestive enzymes, would have an extensive rough ER network, while a : muscle cell would have a large proportion of mitochondria to make the large amount of energy necessary for muscle contraction. 95. Why are chloroplasts and mitochondria believed to have originated from ancient prokaryotes? ANSWER: Both mitochondria and chloroplasts contain DNA, RNA, and ribosomes that resemble those found in bacteria. 96. Why is cartilage relatively soft while tendons are tough and elastic? ANSW Cartilage contains a high proportion of interlinked glycoproteins, which make it soft. Tendons are made ER: of almost pure collagen, which is tough and elastic. Copyright Cengage Learning.
