AP Biology 2.10.A Endosymbiosis and Cell Compartmentalization

Practise AP Biology 2.10.A questions by comparing prokaryotic and eukaryotic compartmentalization and evaluating evidence for endosymbiotic organelle origins.

Exam points

distinguish membrane-bound organelles and internal regions in eukaryotic and prokaryotic cells
use organelle DNA, ribosomes, membranes or replication as endosymbiosis evidence
map prokaryotic structures to functions performed by eukaryotic organelles

[Maximum number: 1]

Mitochondria have their own DNA and divide independently of the cell.

Mitochondria can carry out hydrolytic reactions on organic molecules.

Mitochondria have a highly folded membrane.

Mitochondria are found in both plants and animals.
