Answer :
The plant cell, like the animal, is eukaryotic, that is, it has a nucleus delimited by a nuclear membrane (karyotheca). In addition to this characteristic, these cells have a plasma membrane and cytoplasm, structures common to any cell.
What are the three main lines of evidence that mitochondria arose from endosymbiosis with proteobacteria?
"Some organelles (mitochondria and chloroplasts) existing in eukaryotic cells emerged thanks to a symbiotic association. It is believed that mitochondria and chloroplasts are descendants of prokaryotic organisms that were captured and adopted by some cell, thus living in symbiosis."
With this information, we can conclude that After engulfing the cell, it remained maintained in the cytoplasm of the host cell without degradation. The two organisms then began to live in symbiosis and were later unable to live in isolation. The prokaryote likely benefited the host cell with the process of respiration (mitochondria) and photosynthesis (chloroplast), and the host cell provided protection and nutrients.
