Since the spinal cord injury is above the origin of the phrenic nerve it means that it will be lost the function of this nerve.
The phrenic nerve controls the diaphragm muscle, which controls the breathing process.
If the nerve is damaged and signals between the brain and
the diaphragm are interrupted, normal breathing won't be possible.

Answer:
Nucleus
Explanation:
Prokaryotes are the organism that came earlier than eukaryotes on this earth. These prokaryotes do not have a nucleus and other membrane-bound organelles like chloroplast, mitochondria, Golgi apparatus, endoplasmic reticulum, etc.
So as prokaryotes lack membrane-bound organelle their genetic material is not enclosed in the nucleus therefore their genetic material remains in the cytoplasm of the cell while eukaryotes have membrane-bound nucleus in which their genetic material are present.
So the nucleus is the major organelle that prokaryotes are missing that eukaryotes have.
