Root Explanation

Plasmalemma → It is formed from "plasma" (from Greek "plasma", meaning something molded or formed) and "lemma" (from Greek "lemma", meaning a husk or sheath). The word "plasmalemma" refers to the membrane surrounding a cell, which can be thought of as the 'sheath' that contains the 'formed' cellular material.

Memory Tip

Think of 'plasma' as the 'formed' material inside a cell, and 'lemma' as the 'sheath' that surrounds it. This helps you remember that 'plasmalemma' is the membrane that encases the cell's contents.
