Endosymbiotic Theory

Front

What is the Endosymbiotic Theory?

Back

The Endosymbiotic Theory explains the origin of eukaryotic cells from prokaryotic organisms through a symbiotic relationship.

Front

What evidence supports the Endosymbiotic Theory?

Back

Mitochondria and chloroplasts have their own DNA, which is similar to prokaryotic DNA.

Front

What organelles are believed to have originated from the Endosymbiotic Theory?

Back

Mitochondria and chloroplasts.

Front

How do mitochondria and chloroplasts replicate?

Back

They replicate via binary fission, similar to prokaryotic cells.

Front

Where is DNA located in a prokaryotic cell?

Back

DNA is found floating around in the cytoplasm.

Front

What is the significance of prokaryotic ribosomes in the Endosymbiotic Theory?

Back

The presence of prokaryotic ribosomes in mitochondria and chloroplasts supports the idea that these organelles originated from prokaryotic cells.

Front

What role did endocytosis play in the Endosymbiotic Theory?

Back

Endocytosis allowed early eukaryotic cells to engulf prokaryotic cells, leading to a symbiotic relationship.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and organelles.

Front

What is a key characteristic of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, generating ATP through cellular respiration.

Front

What is a key characteristic of chloroplasts?

Back

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