Which one of the following statements about endosymbiosis and the origin of the eukaryotic cell is false?

1. the chloroplasts of red and green algae are the descendants of cyanobacteria.
2. ultimately, both the chloroplast and the mitochondria of eukaryotes are descendants of prokaryotic cells.
3. many compartments of the eukaryotic cell are derived from the endomembrane system.
4. algae incorporated prokaryotic cells that became chloroplasts, but never acquired mitochondria.
5. mitochondria are the descendants of purple bacteria.

Answer is 4. Algae incorporated prokaryotic cells that became chloroplasts, but never acquired mitochondria.

Explanation:

It should be noted , that symbiosis or symbiotic relationship is a type of relationship involving two organisms where, one may benefits while the other suffers or both organisms benefit. Symbiosis, may involve one organism living inside or outside the other.

In a situation, whereby one of the organisms involved lived inside the order , is being referred to as endosymbiosis.

This endosymbiosis has been described as probably a means through which the eukaryotic cells got or developed some organelles like chloroplasts and mitochondria.
