Nothing wrong with you, having absorbed energy from plant (5)
I believe the answer is:
oxeye
'plant' is the definition.
(oxeye is a kind of plant)
'nothing wrong with you having absorbed energy' is the wordplay.
'nothing' becomes 'O' (looks like zero - 0).
'wrong with' becomes 'x' (X is used to mark something as incorrect. I am not sure about the 'with' bit.).
'you' becomes 'ye' (historical version of 'you').
'having absorbed' is an insertion indicator.
'energy' becomes 'e' (physics symbol as in E=mc2).
'x'+'ye'='xye'
'xye' placed around 'e' is 'xeye'.
'o'+'xeye'='OXEYE'
'from' is the link.
(Other definitions for oxeye that I've seen before include "Variety of daisy" , "Kind of daisy" , "Daisy plant" , "White and yellow daisy" , "Wild chrysanthemum" .)
