Root Explanation

Pseudocoelomate → It is formed from "pseudo-" (meaning false) and "coelom" (from Greek "koilos", meaning hollow or cavity) and the suffix "-ate" (indicating a condition or state). The term describes an organism that has a false coelom, which is a body cavity that is not completely lined by mesoderm.

Memory Tip

Think of 'pseudo-' meaning false and 'coelom' referring to a hollow space — a pseudocoelomate is an organism with a false body cavity.
