Which of the following cells possess Nissl's granules?
- A. Nerve cells
- B. WBC
- C. RBC
- D. Platelets
Explanation
Nissl granules are stacks of rough endoplasmic reticulum in the cell body of a neurone, supporting the heavy protein synthesis a nerve cell requires. Mature red blood cells have no nucleus and almost no organelles at all, and platelets are only cell fragments. Their loss after injury, called chromatolysis, is a recognised sign of neuronal damage.
