Question 1 What part of the cell serves as the intracellular highway? 2 D a Structure 1 b Structure 2 Structure 3 Structure 4

Answer 1

The part of the cell that serves as the intracellular highway is the endoplasmic reticulum (ER). The ER is responsible for transporting proteins and other materials throughout the cell. If you have images or diagrams labeled as Structure 1, Structure 2, etc., please provide them for more specific identification. Without those, I can only tell you that the endoplasmic reticulum plays a critical role in cellular transport.
