Answer:
Plant cells having chloroplasts suggests that they come from a specific species of prokaryotes: cyanobacteria.
Explanation:
The endosymbiosis theory explains that <u>eukaryotic cells</u> (both plant and animal cells) <u>come from a common ancestor: prokaryotes</u>. Chloroplasts and mitochondria have outer phospholipid bilayer membranes and circular DNA molecules like prokaryotes have.
It is believed that ancient bacteria were captured by other cells in the past and thus they became eukaryotic cells.
Cyanobacteria are prokaryotes with the capacity to do photosynthesis as plant cells do.
