Which of the following is a mesh of interconnected membranes involved in protein synthesis and transport?
Correct answer: A. Endoplasmic Reticulum (ER)
- A. Endoplasmic Reticulum (ER)
- B. Cytoskeleton
- C. Golgi apparatus
- D. All of these
Explanation
The correct answer is the Endoplasmic Reticulum (ER), which is a network of interconnected membranes involved in protein synthesis and transport. The cytoskeleton provides structural support and does not participate directly in protein synthesis or transport. The Golgi apparatus is responsible for further processing and packaging proteins but does not synthesize them. Therefore, the only organelle described as a 'mesh of interconnected membranes' involved in both protein synthesis and transport is the ER.
