Use the word bank to complete the followingPractice: Released Cell Structure Multiple Choice and FRQ1. Liver cells are specialized cells that carry out a multitude of tasks, including the synthesis of cholesterol. These cells would be expected to contain a large proportion of which organelle relative to all others?a.golgi bodyc.smooth ERb.rough ERd.ribosomes2. Membrane-bound organelles have been an important component in the evolution of complex, multicellular organisms. Which of the following best summarizes an advantage of eukaryotic cells having internal membranes?a.Eukaryotic cells are able to reproduce faster because of the presence of organelles.anelles isolate specific reactions, increasing metabolic efficiency.b.Some organelles, such as mitochondria and chloroplasts, are similar to prokaryotic cells in structure.partmentalization leads to a higher mutation rate in DNA, which leads to more new species.3. Specialized cells in the adrenal gland produce the hormone epinephrine and store it in vesicles. To release epinephrine these vesicles are carried to the plasma membrane and fuse with it. Which cellular organelles are involved in this process?a.lysosome, Golgi body, cell membranec.Rough ER, Golgi body, nucleusb.Golgi body, cell membrane, vesicled.Ribosome, Smooth ER, vesicle4572000683895004. Various materials are transported into or out of the cell by diffusion. (The formula for the surface area of a cube is 6 x S 2 , and the formula for the volume of a cube is S 3 , where S = the length of a side of the cube.) Which of the following cube-shaped cells would be most efficient in removing waste by diffusion?Practice FRQ: Write on a separate piece of paper 1. During an investigation of a freshwater lake, an AP Biology student discovers a previously unknown microscopic organism. Further study shows that the unicellular organism is eukaryotic. Identify FOUR organelles that should be present in the eukaryotic organism and describe the function of each organelle.Prokaryotic cells lack membrane-bound organelles found in eukaryotes. However, prokaryotes must perform many of the same functions as eukaryotes. For THREE of the organelles identified in part (a), explain how prokaryotic cells carry out the associated functions. According to the endosymbiotic theory, some organelles are believed to have evolved through a symbiotic relationship between eukaryotic and prokaryotic cells. Describe THREE observations that support the endosymbiotic theory. ................
