Plate shaped like part of flower (5)
I believe the answer is:
petal
'part of flower' is the definition.
(I've seen this before)
'plate shaped' is the wordplay.
'shaped' is an anagram indicator.
'plate' anagrammed gives 'PETAL'.
'like' is the link.
(Other definitions for petal that I've seen before include "Floral segment" , "Flowery term of endearment?" , "Brightly-coloured part of flower" , "Plate (anag.)" , "A bit of flower" .)
