IPA: /ˈɑːrθrəspɔːr/
KK: /ˈɑrθrəˌspɔr/
A type of resting cell found in some bacteria and fungi, previously thought to be a spore, that can form chains and is involved in reproduction.
The arthrospores of the fungus were observed under the microscope, showing their characteristic chain formation.
Arthrospore → It is formed from "arthro-" (from Greek "arthron", meaning joint) and "spore" (from Greek "spora", meaning seed or to sow). The word refers to a type of spore that is formed at the joints of a fungal hypha, thus combining the concepts of joint and seed.
Think of 'joints' ('arthro-') where 'seeds' ('spore') are produced — that's how arthrospores are formed.
