The Attributes (a description) of a Cell...
  
A living cell may be described as a(n)...
... self contained...  self assembling...  self adjusting...  self perpetuating... 
   
           
isothermal (steady & ambient) mix of biomolecules,
... held in a 3-D conformation by
weak non-covalent forces,
... that 
extracts precursors & free energy from its surroundings,
... that maintains a quantum state far from equilibrium,
... & that can
catalyze reactions with specific biocatalysts (enzymes), 
              which it makes itself ,
... & that shows great efficiency & economy of
metabolic regulation,
... & can
self-replicate
, using the linear information in the
              "molecule of life"… 
DNA.
                                                                    
                       
  
But where did the first cells come from?
