Guia de Aprendizaje 2: Eucariotas: origen y sus membranas celulares GRUPO 1 1. The hallmark of eukaryotic cells is compartmentalization. Membrane- enclosed organelles process information, transform energy, form internal compartments for transporting proteins, and carry out intracellular digestion. An internal cytoskeleton plays several structural roles. a. What are some advantages of organelle compartmentalization? See p. 84 b. Describe the structural and functional differences between rough and smooth endoplasmic reticulum. See pp. 88–90 and Figure 5.9 c. Explain how motor proteins and microtubules move materials within the cell. See pp. 97–98 and Figures 5.18, 5.19 GRUPO 2 2. Eukaryotic cells arose long after prokaryotic cells. Some organelles may have evolved by infolding of the plasma membrane, whereas others probably evolved by endosymbiosis. a. How could membrane infolding in a prokaryotic cell lead to the formation of the endomembrane system? See p. 101 and Figure 5.23A b. Expla
