A plant takes up nitrate ions at its roots and they arrive in a leaf at the top of the stem. Which statements about that journey are true? Select all that apply.

Erklärung

Mineral ions dissolve in the water a root absorbs and are swept along with it in the water-carrying tissue, so they reach the leaf by exactly the same route as the water itself. Carrying dissolved minerals is not the same as carrying food: food here means the sugar a plant builds, and that is loaded into the other tissue only after a leaf has made it.
