D. Mitochondria can fuse together to form larger organelles within eukaryotic cells.
Which of the following statements is correct? Please select all that apply.
Select one or more:

Parasitism between bacteria and archaea caused complex interactions that eventually gave rise to eukarya.
b.
While bacteria are prokaryotes, archaea are neither prokaryotic, nor eukaryotic but classified as a 3rd cell type.
c.
Prokaryotes are classified further based on whether they are unicellular or multicellular organisms.
d.
The molecular biologies of archaea and eukarya show a greater proportion of similarities than those of eukarya and bacteria.
e.
Prokaryotes could not make photosynthesis until chloroplast endosymbiosis evolution.
