Both euglena and cyanobacteria are photosynthetic unicellular organisms found in pond water. Many features are shared between these organisms and the universal common ancestor, but some characteristics are more recent adaptations. The feature that is only present in the euglena and not in cyanobacteria as a result of common ancestry must be the —

• ability to maintain homeostasis

• presence of ribosomes

• ability to reproduce

• presence of a nuclear membrane

Which of these statements correctly identifies the endosymbiosis theory of eukaryotic cell evolution?

• A eukaryotic cell ingested a mitochondria which then turned into a chloroplast.

• A prokaryotic cell ingested another prokaryotic cell, which is what we now consider a mitochondria or chloroplast inside of a eukaryotic cell.

• A prokaryotic cell combined with a eukaryotic cell to create a eukaryotic cell containing a mitochondria or chloroplast.

• A prokaryotic cell grew a mitochondria and chloroplast when it needed energy and became the basis of a eukaryotic cell.
