Concept:In both plants and animals, transport of materials and hormones occurs through a liquid or fluid medium.
Explanation:In plants, water and dissolved minerals are carried in xylem vessels, while organic nutrients and hormones move through phloem in a fluid form.
In animals, blood plasma is the main fluid medium that carries dissolved nutrients, gases, waste products, and hormones around the body.
Therefore, a key similarity is that transported materials and hormones are moved in fluid form in both systems.
The other statements are not correct.
The transport medium is not made of tissues only, because it also contains fluid such as blood plasma, xylem sap, or phloem sap.
Plant and animal transport do not use the same vessels.
Diffusion is still required in some stages of transport, such as movement into and out of cells.
Answer:A. Materials and hormones are transported in fluid form.
