Root Explanation

Acrosome is formed from "acro-" (from Greek "akron", meaning tip or extremity) and "soma" (from Greek "soma", meaning body). The word refers to a structure at the tip of a sperm cell, which is crucial for fertilization, hence the meaning related to the tip of the body of the sperm.

Memory Tip

Imagine the 'tip' ('acro-') of a 'body' ('soma') — the acrosome is the tip of the sperm's body that plays a vital role in fertilization.
