What is the main mode of transport for mineral ions in a plant?
Active uptake
Passive uptake
Transpiration stream
Diffusion
Solution
After reaching the xylem through active or passive uptake, or a combination of the two, the further transport of the mineral ions to all parts of the plant is through the transpiration stream. The xylem exudates analysis also shows that the transport of some elements, like nitrogen, is carried in the organic form, while others like phosphorus and sulfur are carried in inorganic form.
