I was reading about cell biology, and they mentioned something called an endosome.

Oh really? What’s an endosome?

It’s like a vesicle that helps transport molecules inside the cell.

That sounds fascinating! Cells are so complex.

Root Explanation

Endosome → It is formed from "endo-" (meaning within) and "soma" (from Greek "soma", meaning body). The word "endosome" refers to a membrane-bound compartment within a cell, thus indicating a body that is located within another body.

Memory Tip

Think of 'endo-' meaning 'within' and 'soma' meaning 'body' — this helps you remember that an endosome is a body found within a cell.
