During the light independent reaction, carbon dioxide is fixed by adding it to a

By adding it to a 5-carbon compound.  

In plants, carbon dioxide gets inside the leaf with the help of spores known as stomata and disperses into the stroma of the chloroplast, the location of the Calvin cycle reactions. These reactions are also known as light-independent reactions, as they are not directly mediated by light.  

In the Calvin cycle, the carbon atoms from carbon dioxide are fixed and are utilized to generate three carbon sugars. One of the stages of the Calvin cycle is carbon fixation. In carbon fixation, a molecule of carbon dioxide merges with a five-carbon acceptor molecule, RuBP (ribulose-1,5-bisphosphate), catalyzed by the enzyme rubisco.  

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.
