Notes- Alternate photosynthesis

Open Ended

Why is it important for plants to have different types of metabolisms?

Multiple Choice

How does photorespiration affect the rate of photosynthesis?

• Increases the rate of photosynthesis

• Decreases the rate of photosynthesis

• Doesn't affect the rate of photosynthesis

Multiple Choice

What is photorespiration and why is it considered bad for C3 plants?

• It produces sugar and is beneficial for the plant

• It produces CO2 and sugar

• It produces CO2 but no sugar, which is bad for the plant

• It produces oxygen and sugar

Open Ended

Explain how plants in hot, dry climates have adapted their carbon fixation mechanisms to survive.

Fill in the Blank

The spatial separation of steps in C4 plants involves fixing CO2 in the ___ cells before transferring it to bundle sheath cells.

Multiple Select

Which of the following are examples of C4 plants?

• Pineapple

• Maize (corn)

• Jade

• Sugarcane

Open Ended

Compare the leaf structure of C3 and C4 plants as shown in the diagram. What is the main difference in the arrangement of bundle sheath cells?

Multiple Choice

Which process in CAM plants allows them to conserve water in arid environments?

• Opening stomata during the day

• Storing CO2 in organic acids at night

• Fixing CO2 in bundle sheath cells

• Releasing CO2 during the night

Open Ended

Reflecting on today's lesson about plant metabolism and stomata, what is one question you still have or one concept you would like to explore further?

Multiple Choice

What is the primary function of the Calvin Cycle in photosynthesis?

• To produce G3P, a precursor to glucose and other organic molecules

• To absorb sunlight for energy

• To break down glucose into ATP

• To transport water through the plant
