Membrane-bound organelles. Eukaryotic cells contain collections of proteins that function as a unit called organelles. Some of these organelles are surrounded by a membrane similar in structure to the cell membrane but with a different composition of protein and phospholipid.Membrane-bound organelles offer several advantages to eukaryotic cells.ome of these organelles are surrounded by a membrane similar in structure to the cell membrane but with a different composition of protein and phospholipid.
