Endosymbiotic theory - ANSWER Explains how larger prokaryotic cells engulfed
smaller prokaryotic cells. These smaller cells inside the larger cell evolved into
organelles over time.
Mitochondria and chloroplasts - ANSWER What organelles evolved from smaller
prokaryotic cells?
Evidence that mitochondria and chloroplasts evolved from free-living prokaryotes -
ANSWER - they have a double membrane
- They can convert their own energy energy
- They have similar DNA to bacteria
- They have the same ribosomes as bacteria
- They reproduce the same way as bacteria
- They are the same size and shape as bacteria
Larger Prokaryotic Cell - ANSWER This cell engulfed the smaller prokaryotic cells
and benefited from the energy they supplied
Plant cells - ANSWER Larger prokaryotic cells that engulfed both small
photosynthetic prokaryotes and small heterotrophic prokaryotes evolved over time
into these types of cells
Animal Cells - ANSWER Larger prokaryotic cells that only engulfed the smaller
heterotrophic prokaryotes evolved over time into these types of cells
Why do mitochondria and chloroplasts have two cell membranes? - ANSWER The
inner membrane is from the original prokaryote and the outer membrane is from the
larger prokaryote that engulfed it
How did the larger prokaryotic cell benefit from the symbiotic relationship with the
smaller prokaryotes? - ANSWER It was able to get additional energy from the
smaller prokaryotes inside of it
How did the smaller prokaryotic cells benefit from the symbiotic relationship with the
larger prokaryote? - ANSWER They were protected from the harsh outside
environment and other large cells
Symbiotic Relationship - ANSWER A special type of interaction between different
species. Sometimes beneficial, sometimes harmful, these relationships are essential
to many organisms and ecosystems, and they provide a balance that can only be
achieved by working together.
