Plant reproductive body (5)
I believe the answer is:
spore
'plant reproductive body' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for spore that I've seen before include "Fungal cell" , "Fungus reproducer" , "Ropes (anag.)" , "Reproductive body produced by fungi" , "Asexual reproductive body" .)
