Calvin cycle

LIGHT- INDEPENDENT
STAGE OF PHOTOSYNTHESIS

, Lesson objective
• Explain the processes occurring in the dark
phase of photosynthesis

, Success criteria
• Explain the Calvin cycle in terms of inputs and products produced.
• Analyse how the products from the light dependent reaction are used in the
Calvin Cycle.
• Identify materials which are returned to the light dependent stage.
• Identify and explain acceptors and donors in the light independent stage

• Identify and explain oxidised and deoxidised molecules in the light

dependent stage
• Describe how Benson and Calvin’s work contributed to providing evidence

for the dark phase
• Explain which substances enter the Calvin cycle from outside the

photosystem by identifying the products they form
• Indicate the number of carbon atoms in each molecule associated with the

Calvin cycle
• Discuss how radioactive isotopes in tracing pathways were used when

discovering the dark phase
