Mineral nutrients absorbed by roots, move to leaves through

A

xylem

B

phloem

C

sleve tube

D

companion cell

Text Solution

Verified by Experts

The correct Answer is:
A
Mineral salts absorbed by the roots move laterally from epiblema to xylem through cortex, endodermis and percycle. Finally, they are transported upwards through xylem alongwith the transpiration stream. Some upward translocation of mineral salts also occurs in the phloem under certain circumstances.

How many of the following statements are not correct? [I] In a flowering plant the substances that would need to be transported are water, mineral nutrients, organic nutrients and plant growth regulators. [II] Over small distances, substances move by diffusion and by cytoplasmic streaming supplemented only by passive transport. [III] Organic and mineral nutrients undergo multidirectional transport through the xylem. [IV] From the storage organs, organic compounds are later re-exported. [V] Phytohormones and other chemical signals are transported to maintain and regulate the plant functions.

Minerals absorbed by the roots travel up the xylem. How do they reach the parts where they are needed most ? Do all the parts of the plant get the same amount of the minerals ?
