Origin of Eukaryotic Cells
Texto del Guión Gráfico
- The Endosymbiotic Theory states that after large cells engulfed small cells, the small cells survived and evolved to become membrane-bound organelles, creating eukaryotic cells that originate approximately 2 billion years ago.
- We are Eukaryotes, cells with a nucleus and membrane bound organelles!
- Who are you?
- Membrane-bound organelles, such as mitochondria and chloroplasts, evolved from prokaryotic organisms, a single-cell organism without a nucleus or other membrane-bound organelles.
- Eukaryotic cells were able to develop new characteristics, such as multicellularity, cell specialization, and large size.
- Wow, what happened to you?
- How did you get there?
- Evolution is the process of living organisms diversifying from previous ancestors. Cells evolved over millions of years, developing traits such as nervous systems, fins, and legs, that eventually helped organisms move to land.
- Over millions of years, the eukaryotic cells grew more complex, so their DNA evolved and diversified until they grew into multicellular organisms.
