Photosynthesis

What is the function of NADPH and ATP?

• They absorb light
• They provide energy for the light reactions

• They provide electrons for the dark reactions

• They provide energy and electrons for dark reactions

Where do the dark reactions (Calvin cycle) take place?

• thylakoid membrane

• lumen

• stroma

Most plants appear green because chlorophyll

• absorbs green light.
• absorbs violet light.
• does not absorb green light.
• does not absorb violet light.

What do pigments do?

• Absorb specific wavelengths(color) of visible light for energy.

• Absorb CO₂ in the Stroma to create sugar.

• Transports e^- in the electron transport chain.

• Transports energy between plant cells.

What is the useful end product of photosynthesis?

• carbon dioxide
• water
• glucose
• methane

What is the waste product of photosynthesis?
