The term "cycle" is not used to describe the light-independent reactions of photosynthesis. Instead, they are more accurately called the Calvin Cycle.

Here's why:

* Calvin Cycle: This term specifically refers to the series of biochemical reactions that take place in the stroma of chloroplasts, utilizing the energy from ATP and NADPH produced in the light-dependent reactions to convert carbon dioxide into glucose.

* Cycle: This term implies a recurring series of events, which is accurate for the Calvin Cycle as it involves a continuous flow of molecules through a series of reactions.

While "light-independent reactions" is a valid term, it's less specific than "Calvin Cycle." Using the term "Calvin Cycle" emphasizes the unique and important set of reactions that occur in the stroma and are central to carbon fixation in photosynthesis.
