Cell Compartmentalization - AP Biology

Front

What organelles are known to have arisen from endosymbiosis?

Back

Chloroplasts and mitochondria.

Front

What does the theory of endosymbiosis explain?

Back

The origin of eukaryotes.

Front

What unique characteristic do mitochondria and chloroplasts share compared to other organelles?

Back

They were once free-living prokaryotes.

Front

Why is it advantageous for cells to be small?

Back

To maintain a lower volume to surface area ratio.

Front

What are the two organelles that arose from endosymbiosis?

Back

Mitochondria and chloroplasts.

Front

What is the primary function of mitochondria in eukaryotic cells?

Back

To produce ATP through cellular respiration.

Front

What is the primary function of chloroplasts in plant cells?

Back

To conduct photosynthesis.

Front

How does the endosymbiotic theory support the idea of a common ancestry among eukaryotes?

Back

It suggests that eukaryotic cells evolved from a symbiotic relationship between different species of prokaryotes.

Front

What evidence supports the endosymbiotic theory?

Back

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

Front

What is the significance of the surface area to volume ratio in cells?

Back

A higher surface area to volume ratio allows for more efficient exchange of materials with the environment.
