Surface tension
________ is a force that exists among water molecules at an air- water interface.
Cohesion
________ is molecular action among like molecules, such as the hydrogen bonding that occurs among molecules in water.
Casparian strip
The ________ does not affect water and ions that move through the plastic route.
Adhesion
________ is a molecular attraction among dissimilar molecules.
Endodermal cells
________ are tightly packed and secrete a narrow band of wax called the Casparian strip.
Phloem
________ consists largely of two cell types, sieve- tube elements, and companion cells.
vascular plants
In ________, a source is a tissue where sugar enters the phloem; a sink is a tissue where sugar exits the phloem.
movement of ions
The ________ and water into the root xylem is responsible for the process known as root pressure.
sieve
They are connected to one another, end to end, by perforated ________ plates.
Sieve tube elements
________ lack nuclei and most other organelles.
Casparian strip
The ________ blocks the apoplastic route by preventing water from moving through the walls of endodermal cells and into the vascular tissue.
In this case, the water interacts with a solid substrate
such as the glass walls of a capillary tube or the cell walls of tracheids or vessel elements-through hydrogen bonding
water potential
indicate the potential energy that water has in a particular environment compared with the potential energy of pure water at room temperature and atmospheric pressure
solute potential
tendency for water to move in response to differences in solute concentrations is determined by the ____.
Well pressure
The force exerted by the wall
turgor pressure
As water moves into the cell, the pressure of the fluid contents inside the cell
suberin
forms a waterproof barrier where endodermal cells contact each other
root pressure
Movement of ions and water into the root xylem is responsible for the process known as ___.
