I'm a little stuck... Click here to teach me more about this clue!

'cell' is the definition.
Both the answer and definition are singular nouns.
Maybe there's a link between them I don't understand?

'kid riding moose trashed' is the wordplay.
'kid' becomes 'rib' (I've seen this in another clue).
'riding' is a charade indicator (letters next to each other) (in a down clue, some letters go on top of others).
'trashed' is an anagram indicator.
'moose' with letters rearranged gives 'osome'.
'rib'+'osome'='RIBOSOME'

'part of' acts as a link.

Can you help me to learn more?

(Other definitions for ribosome that I've seen before include "Cellular particle" , "DNA and protein particle; boom rise (anag.)" .)

I've seen this clue in the Sydney Morning Herald.
