Miller Levine Lesson 8.3

Multiple Choice

Which of the following is the best description of the process shown in the image below?

• Water, oxygen, and light are inputs while carbon dioxide and glucose are outputs

• Water, oxygen, carbon dioxide, and light are inputs and glucose is the output

• Water, carbon dioxide, and light are inputs while oxygen and glucose are outputs

• Glucose, oxygen, and light are inputs while carbon dioxide and water are outputs

Multiple Choice

Which of the following is NOT a necessary input for the process of photosynthesis?

• CO₂ (carbon dioxide)

• Sunlight

• H₂O (water)

• O₂ (oxygen)

Multiple Choice

Where within the cell does photosynthesis take place?

• cytoplasm

• chloroplasts

• mitochondria

• nucleus

Multiple Choice

Which of the following can be used to measure the rate of photosynthesis?

• light intensity (%)

• oxygen production (mL/hr)

• temperature

• CO₂ level

Multiple Choice

According to the graph below, what temperature will result in the highest rate of photosynthesis?

• 5°C

• 40°C

• 30°C

• 25°C

Multiple Choice

Based on what you have observed in the Gizmo, which of the following chemical equations represents photosynthesis?

• Carbon dioxide plus water yields glucose (sugar) and oxygen

• Oxygen plus carbon dioxide yields water and glucose.

• Glucose plus oxygen yields carbon dioxide and water.

• Water plus glucose yields oxygen and carbon dioxide.

Multiple Choice

If chlorophyll were red instead of green, making plants red in appearance, which color of light would you expect to produce the LOWEST rate of photosynthesis?

• white

• blue

• red

• green

Multiple Choice

The photosystems contain pigments that absorb light and pass the energy on to

• NADPH

• ATP

• electrons

• ADP

Multiple Choice

The major products of the light-dependent reactions are

• ATP & NADPH

• NADPH & water

• carbon dioxide & water

• ATP & sugars

Multiple Choice

In photosynthesis, carbon dioxide is used to make sugars during

• ATP formation

• Calvin Cycle

• light-dependent reactions

• electron transport chain

Multiple Choice

What is the function of NADPH and ATP in the Calvin cycle?

• they provide the energy required to build high-energy sugars

• they provide energy to create needed oxygen

• they provide energy to expel CO₂

• they provide enough energy for it to be stored for long periods

Multiple Choice

How do CAM plants photosynthesize under bright hot conditions without drying out?

• by allowing small openings in their leaves to admit more carbon dioxide

• by lowering the amount of ATP required for the Calvin cycle

• by using the C4 pathway

• by sealing their leaves against water loss & trapping carbon as organiz acids
