A student designs a set-up to investigate germinating seeds. He fills the jar with seeds that have soaked in
water. In the jar, he places a beaker that contains a solution of bromothymol blue. Bromothymol blue turns
green in the presence of carbon dioxide. He will record his observations on Day 1, wait 24 hours, and record his
observations again on Day 2. The expermental set-up is shown below.
Which question has the student MOST LIKELY asked to set up this investigation?
a. Do germinating peas release carbon dioxide in the process of respiration?
b. Do germinating peas release water in the process of photosynthesis?
c. Do germinating peas release oxygen in the process of respiration?
d. Do germinating peas absorb water in the process of photosynthesis?
