All of the following are possible origins of cell organelles in eukaryotes except: invagination of the plasma membrane to form endoplasmic reticulum. incorporation of engulfed heterotrophic bacteria to form mitochondria. incorporation of engulfed autotrophic cyanobacteria to form chloroplasts. a symbiotic relationship between a host cell and a prokaryote that was taken up but not destroyed. all of the answer choices are possible explanations.

The correct answer is "All of the answer choices are possible explanations".

Explanation:

The evolutionary origin of cell organelles propose that a some point in history, a symbiotic relationship between prokaryotic cells and the ancestor of eukaryotes occurred. Basically, in this symbiotic relationship, the ancestor of the eukaryotic host cell took up a prokaryote that was not destroyed. There are different theories regarding the origin of the different organelles, including:

- Invagination of the plasma membrane to form endoplasmic reticulum. The endoplasmic reticulum has a tubular networks of membranes that were invaginated.

- Incorporation of engulfed heterotrophic bacteria to form mitochondria. Mitochondria allows for cell's respiration, it is likely that this organelle originated from engulfed heterotrophic bacteria.

- Incorporation of engulfed autotrophic cyanobacteria to form chloroplasts. Chloroplasts allows for cell's photosynthesis, it is likely that this organelle originated from engulfed autotrophic cyanobacteria.

answer; i believe that the correct answer is (b) melosis; plz check first.good luck

not: both offer magnification to the atomic level.
