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

Do mitochondria and chloroplasts have their own nuclei?

Back

False, mitochondria and chloroplasts do not have their own nuclei.

Front

What do both eukaryotic and prokaryotic cells have in common?

Back

Both eukaryotic and prokaryotic cells have ribosomes and cell membranes.

Front

Which organelles are believed to have arisen from endosymbiosis?

Back

Chloroplasts and mitochondria are organelles that definitely arose from endosymbiosis.

Front

What does 'Endosymbiosis' mean?

Back

'Endosymbiosis' means living together.

Front

What is the primary evidence supporting the Endosymbiotic Theory?

Back

The presence of double membranes, circular DNA, and ribosomes similar to prokaryotes in mitochondria and chloroplasts.

Front

How do mitochondria and chloroplasts replicate?

Back

Mitochondria and chloroplasts replicate independently of the cell cycle through a process similar to binary fission.

Front

What role do mitochondria play in eukaryotic cells?

Back

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

Front

What is the function of chloroplasts in eukaryotic cells?

Back

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

Front

What is a key difference between prokaryotic and eukaryotic cells?

Back

Eukaryotic cells have a nucleus and membrane-bound organelles, while prokaryotic cells do not.
