Endocytosis
A cell taking in a substance by surrounding it with its cell membrane
Real World Example
Imagine you're trying to bring a large, awkwardly shaped piece of furniture into your house through the front door. Just like you have to wrap your arms around the furniture to maneuver it through the door, a cell takes in a substance by wrapping its cell membrane around it to bring it inside. In this analogy, your arms are like the cell membrane, the furniture is the substance, and your house is the cell, highlighting how endocytosis involves enclosing and bringing in external materials.
