The Calvin cycle is called the dark cycle because it does not require light to proceed. Unlike light reactions, the Calvin cycle is a light-independent reaction, which means it can and will occur in the dark as well as the light.
Even though light is not needed for the Calvin Cycle, it requires sufficient levels of ATP and NADPH (which are produced from the Light Dependent Reaction). As it is night time, the Light Dependent Reaction will not be 'working' to produce the necessary ATP and NADPH. Therefore, as it is dark, the Light Dependent Reaction will have not produced enough ATP and NADPH to keep the Calvin Cycle going through the night.
it doesn't require light. Thats's why it is also identified as light independent reaction
No, not unless the plant is exposed to light.
The Calvin cycle, or carbon fixation, occurs during the dark reactions of photosynthesis.
The Calvin cycle is part of the light-independent (or "dark") reactions, which take place in the stroma of the chloromoses
Calvin cycle or light independent reaction
The dark reaction (Calvin Cycle) takes place in the chloroplast. More specifically, the stroma.
That is the Dark cycle. Also called Calvin cycle
No, not unless the plant is exposed to light.
the calvin cycle
It cannot occur in the dark. It contains an enzyme called rubisco which is a light-activated enzyme. Also the Calvin cycle uses the chemical energy produced in the light reactions, and the light reactions need sunlight energy in order to produce the energy needed in the Calvin cycle. Hope that helps :)

The Calvin Cycle is also known as the dark phase of photosynthesis.
