Question

In plants, organic and mineral nutrients undergo
(A) Unidirectional transport
(B) Bidirectional transport
(C) Multidirectional transport
(D) Downward unidirectional transport
​

Answer 1

Answer:

Answer:In rooted plants, transport in xylem (of water and minerals) is essentially unidirectional, from roots to the stems. Organic and mineral nutrients however, undergo multidirectional transport. ... The mineral nutrients are taken up by the roots and transported upwards into the stem, leaves and the growing regions.
