Plate shaped like part of a flower (5)
I believe the answer is:
petal
'part of a flower' is the definition.
(I've seen this in another clue)
'plate shaped' is the wordplay.
'shaped' indicates an anagram.
'plate' anagrammed gives 'PETAL'.
'like' is the link.
(Other definitions for petal that I've seen before include "Floral leaf" , "One piece of corolla" , "Bit of blooming" , "Coloured segment of flower" , "Plate (anag.)" .)
