Endosymbiotic Theory

Front

What is the Endosymbiotic Theory?

Back

The Endosymbiotic Theory proposes that eukaryotic cells originated through a symbiotic relationship between different species of prokaryotes, where one prokaryote engulfed another.

Front

What evidence supports the idea that prokaryotes evolved before eukaryotes?

Back

Prokaryotes have no nucleus and fewer genes, indicating they are simpler and likely evolved first.

Front

Where is the DNA located in a prokaryotic cell?

Back

The DNA in a prokaryotic cell is found floating around in the cytoplasm.

Front

Name two organelles that arose from the Endosymbiotic Theory.

Back

Mitochondria and chloroplasts.

Front

True or False: Eukaryotes evolved from prokaryotes through the engulfing of bacteria.

Back

True.

Front

What does the Theory of Endosymbiosis explain?

Back

It explains the origin of eukaryotic cells.

Front

What is a prokaryote?

Back

A prokaryote is a single-celled organism that lacks a nucleus and membrane-bound organelles.

Front

What is a eukaryote?

Back

A eukaryote is an organism whose cells contain a nucleus and membrane-bound organelles.

Front

What role do mitochondria play in eukaryotic cells?

Back

Mitochondria are the powerhouses of the cell, generating ATP through cellular respiration.

Front

What role do chloroplasts play in eukaryotic cells?

Back

Chloroplasts are responsible for photosynthesis, converting light energy into chemical energy.
