The cell membrane is the outer - most boundary of the cell, ribosomes are small structures involved in protein synthesis, the endoplasmic reticulum is a network of membranes for protein and lipid synthesis. Based on the general appearance and location in a typical cell diagram, if 'I' is the central large structure, it is likely the nucleus.
