Root Explanation

Acoelomate → It is formed from "a-" (meaning without) and "coelom" (from Greek "koilos", meaning hollow or cavity) and "-mate" (a suffix used in biology to denote a type or category). The term "acoelomate" refers to organisms that lack a body cavity or coelom, indicating they do not have a hollow space within their body structure.

Memory Tip

Think of 'a-' meaning 'without' and 'coelom' meaning 'hollow cavity' — so an acoelomate is an organism without a hollow body cavity.
