Vascular Plant Transport

Plants transport water and nutrients using a variety of transport systems that are known as the vascular system. Examples of vascular transport include xylem, phloem, and the root system. The phloem is a system of vascular tissue through which the plant gathers food and mineral materials from the soil and carries them to the rest of the plant. The xylem is a system of vessels that transport water and mineral materials from the roots to the rest of the plant. The phloem is a system of tissue through which the plant gathers food and mineral materials from the soil and carries them to the rest of the plant. The xylem is a system of vessels that transport water and mineral materials from the roots to the rest of the plant. The phloem is a system of tissue through which the plant gathers food and mineral materials from the soil and carries them to the rest of the plant. The xylem is a system of vessels that transport water and mineral materials from the roots to the rest of the plant.

Biology: Concepts and Investigations

Suppose that a scientist exposes a leaf to $\mathrm{CO}_{2}$ labeled with radioactive carbon-14, which is incorporated into organic compounds in photosynthetic cells. At various times after exposure, the scientist can determine the location of the radioactive carbon in the plant. In what tissues would you expect to find the radioactive material immediately after exposure to the labeled carbon? What about during transport? When transport is complete, will the radioactive material be in plant parts above the leaf, below the leaf, or both?
