The light-independent reactions of plants function to make organic molecules using carbon dioxide as a carbon source. What is the electron source that helps reduce carbon dioxide to sugars and other organic molecules?

Explanation:

Photosynthesis is a biochemical reaction in which glucose is synthesized by green plants and some other green organisms that have chlorophyll molecule. In this reaction carbon dioxide and water are treated as raw materials. This reaction is completed in two steps, in first step water splits by the sunlight and formation of ATP, NADPH and oxygen molecule takes place so-called as a light reaction.

In the second step no light is required and carbon dioxide is reduced by NADPH so-called light-independent reaction. Since in this reaction electron is transferred by NADPH so considered as an electron source in light-independent reaction.

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.
