Verified step by step guidance1
Identify the key question: Which theory explains the evolution of eukaryotic cells to include membrane-bound organelles?
Understand the context: Eukaryotic cells are characterized by having membrane-bound organelles such as mitochondria and chloroplasts.
Review the theories listed: Theory of Evolution, Endosymbiotic Theory, Germ Theory, and Cell Theory.
Focus on the Endosymbiotic Theory: This theory suggests that eukaryotic cells evolved when one prokaryotic cell engulfed another, leading to a symbiotic relationship. Over time, the engulfed cell became an organelle, such as a mitochondrion or chloroplast.
Conclude that the Endosymbiotic Theory is the most relevant explanation for the presence of membrane-bound organelles in eukaryotic cells.
