IPA: /ˌɛn.dəˈθiː.əm/
KK: /ˌɛndəˈθiːʌm/
The inner layer of tissue found in certain plant structures, such as the anther of a flower or the capsule of a moss.
The endothecium plays a crucial role in the development of pollen grains within the anther.
Endothecium → It is formed from "endo-" (from Greek "endon", meaning within) and "thecium" (from Greek "theke", meaning case or receptacle). The word refers to a structure that is located within a case or receptacle, particularly in botanical contexts.
Think of something that is 'within' ('endo-') a 'case' ('theke') — that's why endothecium refers to a structure inside a case.
