* All human cells have the same basic set of organelles, including the nucleus, mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus, etc.

* Blood cells are human cells. They are specialized cells that circulate within our blood.

What might be confusing you is that some blood cells have unique features that are not found in other human cells. For example, red blood cells lack a nucleus and contain hemoglobin, a protein that carries oxygen.

So, the answer is that there is no organelle found in blood cells that is not also found in other human cells.
