Identify four organelles that should be present in the eukaryotic organism

Identify four organelles that should be present in the eukaryotic organism and describe the function of each organelle.
-Prokaryotic cells lack membrane-bound organelles found in eukaryotes. However, prokaryotes must perform many of the same functions as eukaryotes. For three of the organelles identified in part (a), explain how prokaryotic cells carry out the associated functions.
-According to the endosymbiotic theory, some organelles are believed to have evolved through a symbiotic relationship between eukaryotic and prokaryotic cells. Describe three observations that support the endosymbiotic theory.
