The baking soda solution (NaHCO₃ + H₂O) was the source of carbon dioxide (CO₂) in the experiment. Why is CO₂ important?

• CO₂ is harmful and contributes to global warming

• CO₂ is primarily used in the production of plastics

• CO₂ is a byproduct of photosynthesis

• CO₂ is essential for photosynthesis

Ten leaf disks were punched from four different plants (spinach, strawberry, ivy, and aloe) and sunk in a 2% baking soda solution.  These leaf disks were placed under a light for ten minutes.  The number of floating leaves is graphed below.

Based on the data in the photo, which plant has the highest rate of photosynthesis?

• spinach

• strawberry

• ivy

• aloe

Based on the data in the photo, what patterns do you notice, if any?

• Ivy and aloe have the highest number of floating disks.
• Spinach and strawberry have the highest number of floating disks, while ivy and aloe float less.
• All plants floated equally after ten minutes.
• Spinach and aloe floated the least.
