endoplasmic reticulum
Passive transport is a non-energy requiring process that moves materials across a cell membrane with the concentration gradient. This process includes simple diffusion, facilitated diffusion, and osmosis.

it moves materials from areas of high concentration to areas of low concentrationit moves materials of high concentration to areas of low concentration
The endoplasmic reticulum (ER) is like a highway because it is a network of interconnected tubes that moves materials within the cell, similar to how a highway transports vehicles. Just as a highway allows for efficient transportation across long distances, the ER facilitates the movement of proteins and lipids throughout the cell.
Active transport is the process that moves materials through a cell from areas of low concentration to areas of high concentration. This process requires energy in the form of ATP to pump molecules against their concentration gradient.

The canal network moves certain materials within a cell
Transport proteins that are pumps differ from those that are channels in that when it pumps, it moves materials against concentration gradient. Other wise, from low to high concentration levels. Channels move materials down a concentration gradient, requiring no energy expenditure by the cell. From high concentration to low concentration levels.

The answer is a clock - it moves its hands but doesn't make a sound, while a bell makes a sound but stays in one place.
