Photosynthesis and the Calvin Cycle

What are the two types of reactions in photosynthesis?

• Light-dependent and light-independent reactions

• Calvin cycle and respiration

• Photosystem II and Photosystem I

• Thylakoid and stroma

What is the function of xylem in a vascular plant?

• Conduct water, minerals, and other materials to different parts of the plant

• Absorb sunlight for photosynthesis

• Release oxygen into the atmosphere

• Transport glucose from the leaves to the roots

How does carbon dioxide enter and oxygen exit a plant's leaves?

• Through tiny pores called stomata

• Through the roots via xylem

• Through the chlorophyll in the chloroplasts

• Through the thylakoid membranes

Why do plants need to regenerate RuBP in the Calvin Cycle?

• To continue the cycle and fix more carbon dioxide

• To produce ATP and NADPH for the light-dependent reactions

• To release oxygen into the atmosphere

• To convert G3P into glucose for energy storage

What is the toxic byproduct created by RuBisCo when oxygen is present?

• Phosphoglycolate

• Glucose

• Glyceraldehyde 3-Phosphate (G3P)

• Ribulose Bisphosphate (RuBP)
