'parts of plant' is the definition.
Although both the answer and definition are plural nouns, I cannot see how they can define each other.

'eccentric uncle israel pulled up' is the wordplay.
'eccentric' indicates anagramming the letters.
'israel' becomes 'il' (I've seen this in other clues).
'pulled up' says the letters should be written backwards.
'il' written backwards gives 'li'.
'uncle' is an anagram of 'nucel'.
'nucel'+'li'='NUCELLI'
