The study of cryptogamic plants is essential for understanding ecosystems.
Cryptogamic → It is formed from "crypto-" (from Greek "kryptos", meaning hidden) and "gamia" (from Greek "gamos", meaning marriage or union). The term refers to organisms that reproduce in a hidden or concealed manner, such as fungi and algae.
Think of 'hidden' ('crypto-') organisms that reproduce in a 'union' ('gamia') — that's what cryptogamic refers to.
