Question

Which of the following steps could you take to reduce error in your experiment? Select all that apply -- there are three correct options.

a)Use five different species of potato plants.
b)Keep the potato plants outside prior to the experiment.
c)Have only one person conduct the experiment.
d)Use the same brand of lighting in each chamber.
e)Ensure that all the chambers' gas analyzers are calibrated.
f)Include both healthy and sick potatoes in the experiment.

Answer 1

To reduce error in your experiment, one should consider the following steps:

• d)Use the same brand of lighting in each chamber.
• e)Ensure that all the chambers' gas analyzers are calibrated.
• f)Include both healthy and sick potatoes in the experiment.

Use the same brand of lighting in each chamber. This helps ensure consistency in the light source, reducing the potential for variations in photosynthesis or cellular respiration due to different lighting conditions.

Ensure that all the chambers' gas analyzers are calibrated. Proper calibration of gas analyzers ensures accurate measurement of gas exchange during photosynthesis and cellular respiration, reducing measurement errors.

Also include both healthy and sick potatoes in the experiment. This allows you to account for variations in plant health and their potential impact on photosynthesis and cellular respiration, providing a more comprehensive understanding of the process.
