In biology, the term "pigment" is defined somewhat differently, where a pigment refers to any colored molecule found in a cell, regardless of whether or not it is soluble. The product of this reaction immediately splits in half forming two molecules of PGA, it provides o of the initial reactants (RuBP) of the dark reactions therefore allowing the cycle to occur again and again. They can occur in the light or the dark. Whereas philosophy in general is concerned with the why as well as the how of things, science occupies itself with the latter question only, but in a scrupulously rigorous manner.
