Question

Why is it better to call the dark phase of photosynthesis as a light independent phase?

Answer 1

The dark phase of photosynthesis is known as the light independent phase because it does not requires sunlight.

Explanation:

• Dark reaction is also known as carbon-fixing reaction.
• Sugar molecules are generated from carbon dioxide and water molecules in a light-independent process.
• The dark reaction takes place in the stroma of the chloroplast, where the light reaction's products are used.
• Through stomata, plants take carbon dioxide from the atmosphere and enter the Calvin cycle.
• The Calvin cycle is a reaction that converts six molecules of carbon dioxide into one sugar molecule, glucose, using the ATP and NADPH generated during the light reaction.
