The biologist is performing model-building type of investigation.

Explanation:

In the given scenario it is mentioned that the biologist is making a diorama of a plant cell. The diorama refers to the 3-D model of the specimen or object of the interest. The diorama of the specimen helps in gaining accurate knowledge of the concept as the subject is seen visually.

It also rules out much difference which arises about a concept through theoretical knowledge. Diorama is stable yet highly reliable evidence and it can also be altered according to the research and analysis.
