검증된 단계별 안내1
Understand the endosymbiotic theory: This theory suggests that eukaryotic cells originated through a symbiotic relationship between different species of prokaryotes.
Identify the key event in the endosymbiotic theory: The engulfment of aerobic bacteria by ancestral prokaryotic cells is considered a pivotal event.
Recognize the significance of engulfment: The engulfed aerobic bacteria eventually evolved into mitochondria, providing the host cell with enhanced energy production capabilities.
Consider the evidence supporting this theory: Mitochondria have their own DNA and double membranes, which are characteristics similar to those of prokaryotic cells.
Reflect on the impact of this event: The acquisition of mitochondria allowed eukaryotic cells to become more complex and efficient, leading to the diversity of life forms we see today.
