Why might a scientist use a physical model of a plant cell instead of studying
the cell directly?

A. The model allows the scientist to observe plant cells that are too
large to study directly.

B. The model will show the functions of the cell structures as they
interact within the cell.

C. The model can be changed to give the scientist more accurate
results.

D. The model will enable the scientist to see the microscopic
structures in the plant cell more clearly.
