Photosynthesis Review 2024

Will a photosynthetic organism be able to survive a cave that is cut off from the surface; i.e., there is no light in the cave?

• No, photosynthetic organisms require light to survive even though only 1 of the 2 steps of photosynthesis is dependent on light.
• Yes, photosynthetic organisms only require light to for 1 of the 2 steps of photosynthesis.
• Yes, the organism will simply become heterotrophic and continue to grow and survive.
• No, all autotrophic organisms require light to produce energy.

In the diagram below, which numbered box represents a major product of the light independent reactions?

• 1
• 2 and 4
• 1 and 4
• 4
• 1 and 3

In the diagram below, which numbered box represents the product released by photolysis?

• 1
• 2
• 3
• 4
• None of the above

Which photosynthetic process was first described by Dr. Melvin Calvin?

• Krebs cycle
• Light-dependent reactions
• Light-independent reactions
• Electron transport chain

What would happen to a plant if its chloroplasts lost their thylakoids in a manner that prevented the plant's cells from producing replacements?

• The plant would likely die since the thylakoids are required for the light independent reactions.
• The plant would likely be able to survive since the stroma inside each chloroplast would still be present.
• The plant would likely die since the thylakoids are required for the light dependent reactions.
• There is not enough information to answer the question.
