DOK Level 1: Recall

Why is photosynthesis considered important for life on Earth?

• It produces water and oxygen, which are essential for life.

• It consumes carbon dioxide and helps regulate atmospheric temperatures.

• It is the primary source of organic compounds for most ecosystems.

• All of the above.

DOK Level 1: Recall

Design an experiment to test how light intensity affects the rate of photosynthesis.

• Measure the growth rate of plants under different soil types.

• Compare the oxygen output of plants under varying light intensities.

• Observe the water usage of plants in different seasons.

• Analyze the carbon dioxide levels in sealed environments with plants.

DOK Level 3: Strategic Thinking

Explain how the structure of chloroplasts is adapted to maximize photosynthesis.

• Chloroplasts have a double membrane that protects their internal components.

• The thylakoid membranes provide a large surface area for light absorption.

• Chloroplasts are small and numerous, allowing them to be distributed throughout the cell.

• All of the above are correct.

DOK Level 2: Skill/Concept

Discuss the role of NADPH in the Calvin Cycle.

• It acts as an energy source by providing ATP.

• It provides high-energy electrons needed to reduce carbon molecules.

• It captures light energy and converts it into chemical energy.

• It splits water molecules to release oxygen.
