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' with letters rearranged gives 'PETAL'.
'like' acts as a 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" .)
