organellen.

Brit.

/ˌɔːɡəˈnɛl/, U.S.

/ˈˌɔrɡəˈˌnɛl/

Origin: Formed within English, by derivation perhaps modelled on a German lexical item. Etymons: organ n.¹, -elle suffix.

Etymology: < organ n.¹ + -elle suffix, after organella n. or German Organulum (see organella n.).

Biology.

Any of various discrete, usually membrane-bound, structures within a cell or unicellular organism that perform specialized functions. Cf. earlier organella n.
