Root Explanation

Periplasmic → It is formed from "peri-" (meaning around) and "plasma" (from Greek "plasma", meaning something molded or formed). The term "periplasmic" refers to the space around the plasma membrane of a cell, indicating a region that surrounds or is adjacent to the plasma.

Memory Tip

Think of 'peri-' meaning 'around' and 'plasma' referring to something 'formed' — this helps you remember that 'periplasmic' describes the area surrounding the cell's plasma membrane.
