How do you travel from home to school? Do you take a road, or sidewalk? Roads and sidewalks give people a path to follow as we move about our cities. A cell also has a system of tiny roads. These roads are actually tubes called the Endoplasmic Reticulum.
These clear tubes travel throughout all parts of the cell. Some go from the nuclear membrane to the outside cellular membrane. Others travel to different organelles. Throughout the cell, the endoplasmic reticulum carries materials where they need to go.
Whenever you hear the word endoplasmic reticulum, just think “Cellular Highway”. So climb aboard the endoplasmic reticulum as we prepare to travel to, and explore the rest of the cell.
