Root Explanation

Thylakoid → It is formed from "thylakos" (Greek, meaning pouch or sac) and the suffix "-oid" (meaning resembling or like). The word "thylakoid" refers to a membrane-bound compartment inside chloroplasts that resembles a pouch.

Memory Tip

Imagine a 'pouch' ('thylakos') that is 'like' something else ('-oid') — that's why a thylakoid is a sac-like structure in chloroplasts.
