Reading Challenge - Photosynthesis

Hotspot

Which part of the plant is the site of photosynthesis?

Multiple Choice

Which of the following variables was measured in Ms. Rodriguez's experiment to assess photosynthesis in plants with different leaf structures?

• Rate of oxygen production

• Amount of water absorbed

• Growth rate of plants

• Leaf color change

Multiple Choice

Which plant type produced the highest average amount of oxygen according to the data?

• Broad-Leaf Plant

• Waxy-Leaf Plant

• Needle-Leaf Plant

• Succulent

Multiple Choice

What was the average rate of oxygen production for the Waxy-Leaf Plant?

• 2.5 mL / hr

• 1.2 mL / hr

• 0.8 mL / hr

• 3.7 mL / hr

Multiple Choice

What is the difference in oxygen production between the plant with the highest rate (Broad-Leaf) and the plant with the lowest rate (Needle-Leaf)?

•   1.3  mL  /  hr  

•   3.3  mL  /  hr  

•   0.4  mL  /  

•   1.7  mL  /  hr  

Multiple Choice

Based on the data, why would a waxy-leaf structure be an advantage for a plant in a hot, dry desert?

• It produces more oxygen than a needle-leaf plant.

• Its thick, waxy cuticle helps minimize water loss.

• Its large surface area can absorb more sunlight.

• It is better at surviving in cold climates.
