A team of students encounters an unknown organism in a field while conducting a biodiversity study. Some students think the organism is a plant, while others think it is a fungus. Which question should the students investigate to classify the organism correctly?
A. Is there a cell wall around the cells of the organism?
B. Does the organism perform photosynthesis?
C. Is there nervous tissue present in the organism?
D. Does the organism reproduce sexually?

B. Does the organism perform photosynthesis?

Explanation:

Plants are autotrophic, that is they are capable of making their own food. They carry out photosynthesis, converting light energy to chemical energy which they use.

Fungi on the other hand are heterotrophic, they do not make their own food. They do not carry out photosynthesis.

Hence, ability to perform photosynthesis is an attribute that'll differentiate between fungi and plants.
