1 The former is called qualitative, and the latter quantitative analysis. ( 2 n.) A brief, methodical illustration of the principles of a science. 3  In this sense it is nearly synonymous with synopsis. ( 4 n.) The tracing of things to their source, and the resolving of knowledge into its original principles.
The Calvin Cycle are dark reactions that produce CH20 (Carbohydrates) from CO2. The light reactions produce 02 from H20 and solar energy.
I'm assuming you're talking about photosynthesis. The main difference can be seen in the terms. Light dependent need light to react, light independent do not. In the light reactions the photon of light hits the chlorophyll which excites an electron that goes into the electron transport chain. This electron comes from water being split into H+ ions and oxygent gas.
