The three structures that all animal, plant, bacterial, eukaryotic, or prokaryotic cells have in common are: 1. The cell membrane-a semi-permiable bilayer of lipids allowing â¦ certain molecules to pass through. 2. The cytoplasm-a jelly-like substance that all of the organelles of the cell are suspended in.
Similarities with other cells: 1  Neurons and other body cells both contain a nucleus that holds genetic information. 2  Neurons and other body cells are surrounded by a membrane that protects the cell. 3  The cell bodies of both cell types contain organelles that support the life of the cell, including mitochondria, Golgi bodies, and cytoplasm.
