A student is observing a single-celled alga and knows that it undergoes photosynthesis and respiration. Which question could the student ask to find out how it can do both processes?
a
Is carbon dioxide needed for the process of photosynthesis?
b
Are the inputs of photosynthesis the same as the inputs of respiration?
c
Is water needed for the processes of respiration and photosynthesis?
d
Are the inputs of photosynthesis the same as the outputs of respiration?
d
Are the inputs of photosynthesis the same as the outputs of respiration?
b
Are the inputs of photosynthesis the same as the inputs of respiration?
The question that the student could ask to find out how the alga can undergo both photosynthesis and respiration is:
d) Are the inputs of photosynthesis the same as the outputs of respiration?
To understand how the alga can perform both processes, the student needs to compare the inputs and outputs of photosynthesis and respiration. If the inputs of photosynthesis are the same as the outputs of respiration, it suggests that the alga is capable of recycling the products of respiration back into the process of photosynthesis, enabling it to perform both processes. By asking this question, the student can gain insights into the interconnectedness of photosynthesis and respiration in the alga's cellular processes.
