Which one of the following structures is an organelle within an organelle?
Correct answer: A. Ribosome
- A. Ribosome
- B. Peroxisome
- C. ER
- D. Mesosome
Explanation
Ribosomes are the location of protein synthesis in a cell is a structure, composed of both RNA and protein. They manufacture amino acids and are present inside other cell organelles like mitochondria, chloroplast and endoplasmic reticulum. Hence, they are referred to as organelle within an organelle.
