IPA: /həˈmoʊθəlɪk/
KK: /həˈmōthəˌlik/
Referring to organisms that have both male and female reproductive parts on the same structure, commonly seen in certain fungi and algae.
The homothallic species of fungi can reproduce without the need for a partner.
Homothallic → It is formed from "homo-" (meaning same) and "thalus" (from Greek "thallos", meaning a young shoot or twig). The word describes organisms that can reproduce sexually with themselves or with others of the same type, hence the idea of 'same'.
Think of 'same' ('homo-') and 'young shoot' ('thalus') to remember that 'homothallic' refers to organisms that can reproduce with themselves or others of the same kind.
