Go perhaps to the empty cell (6)
I believe the answer is:
gamete
'cell' is the definition.
(gamete is a kind of cell)
'go perhaps to the empty' is the wordplay.
'go perhaps' becomes 'game' (go is a kind of game).
'empty' means to remove the middle letters.
'the' with its centre removed is 'te'.
'game'+'te'='GAMETE'
(Other definitions for gamete that I've seen before include "Egg- or sperm-cell" , "something seedy?" , "Germ cell in reproduction" , "Male or female germ cell" , "Reproductive unit" .)
