What would happen if the Golgi bodies in the cell were destroyed?
The cell would not be able to digest or break down the materials left over from protein creation.
Explanation:
Without a Golgi apparatus, there would be no lysosomes in a cell. Subsequently, the cell would not be able to digest or break down the materials left over from protein creation. This would create a lot of excess junk within the cell. If this happened, the cell wouldn't be able to live for very long.
