Plants have internal transportation systems that help move food, water, and minerals through the plant. The plant's food, sugar, is produced by the leaves of the plant. Water and minerals are absorbed by the roots. The following diagram is a model of the transportation systems in a plant.

What is one advantage of using this model?
A.
It clearly shows the general directions that food, water, and minerals must move.
B.
It gives a complete picture of the methods used to transport resources to all parts of the plant.
C.
It has parts that are the same size and shape as the components they represent.
D.
It provides details about the ways that the transportation systems work with other parts of the plant.
