Question
Chapter 21.6, Problem 2MC
Summary Introduction
To trace:
The path followed by water and dissolved minerals to move from the soil into the root’s xylem up to the leaves.
Introduction:
Xylem is a vascular tissue that transports water and dissolved minerals to fruits, roots, stems, and other parts of the plant. The cohesion-tension theory explains the movement of xylem sap within a plant.

Students have asked these similar questions
Explain the alternative routes for the uptake of water and dissolved nutrients in roots. Highlight the processes and structures involved.
Water absorption from the soil with the help of
root hairs involves which types of forces?
Which of the following processes enables a plant to extract nutrients from the soil?
O Nutrient anions (sulfate, phosphate, nitrate, etc) are replaced by Cl on soil particles. Released nutrients
become available in the soil water.
Anions exchange places with cations during anion exchange, which confuses roots and turns HATS into LATS,
after which the endodermis synthesizes a caspian endothelium
O Cation exchange facilitates the breaking of covalent bonds between nutrients and soil particles
O Protons replace nutrient cations on soil particles
