Which of the following cell organelles functions both as a passageway for intracellular transport and as a manufacturing surface?

Endoplasmic Reticulum

The correct answer is Option (4)-Endoplasmic Reticulum

The correct answer is: Endoplasmic Reticulum

Explanation: The Endoplasmic Reticulum (ER) is a cell organelle that functions as a passageway for intracellular transport and as a manufacturing surface. There are two types of ER: rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER). The RER has ribosomes attached to its surface, giving it a "rough" appearance, and it is involved in the synthesis of proteins. The SER lacks ribosomes and is involved in lipid synthesis, detoxification, and the storage of calcium ions. Both types of ER play crucial roles in cellular processes.
