Of the following structures, state which ones are unique to neurons and which are not: nucleus, mitochondria, rough ER, synaptic vesicle, Golgi apparatus.

Here’s the classification of the structures based on their uniqueness to neurons:

• Nucleus: Not unique to neurons (found in all eukaryotic cells).
• Mitochondria: Not unique to neurons (found in all eukaryotic cells).
• Rough ER: Not unique to neurons (found in all eukaryotic cells, but its distribution is different in neurons).
• Synaptic vesicle: Unique to neurons (these are specialized structures involved in neurotransmitter storage and release at synapses).
• Golgi apparatus: Not unique to neurons (found in all eukaryotic cells)
