Which cell organelle is absent in neurons?A mitochondria B ribosome C centriole D nucleus

The cell organelle that is absent in neurons is the centriole (C).

Here's a step-by-step explanation:

1. Mitochondria (A): This organelle is present in neurons. It's responsible for producing energy (ATP) through cellular respiration.

2. Ribosome (B): This organelle is also present in neurons. It's responsible for protein synthesis.

3. Centriole (C): This organelle is absent in neurons. Centrioles are involved in cell division, and since neurons do not undergo cell division, they do not have centrioles.

4. Nucleus (D): This organelle is present in neurons. It contains the cell's genetic material (DNA).
