Choose the organelle that you think is the most important for the cell and justify your selection

Eukaryotic and prokaryotic cells can be compared to mini-factories, with multiple organelles working together to perform numerous cellular processes. After reviewing the parts of a eukaryotic or prokaryotic cell:
Choose the organelle that you think is the most important for the cell and justify your selection, describing several key activities this organelle performs. Indicate whether the organelle is in eukaryotic cells, prokaryotic cells, or both.
Which organelle do you think is the least important? Why do you think it is more “expendable” to the cell?
