IPA: /ˌɡæməˈtændʒiəm/
KK: /gæməˈtændʒiəm/
A structure or cell where reproductive cells, known as gametes, are formed in certain plants and fungi.
The gametangium is essential for the reproduction of many algae and fungi.
Gametangium → It is formed from "gameta" (from Greek "gametēs", meaning spouse or marriage) and "-angium" (from Greek "angeion", meaning vessel or container). The word refers to a vessel or container that produces gametes, which are reproductive cells involved in sexual reproduction.
Think of a 'vessel' ('-angium') that holds 'spouse' or 'marriage' ('gameta') — that's why gametangium refers to a structure that produces reproductive cells.
