Chapter 8, Transport in plant

which of these are the lateral pathway of water movement

• Apoplast pathway

• Symplast pathway

• Root Pressure

• Transpiration pull

Water from soil diffuse into root hair cell by...

• Active Transport

• Osmosis

• Evaporation

• Transpiration

Water and dissolved minerals FLOW UP the xylem by

• Root pressure

• Transmembrane pathway

• Pressure flow

• Transpiration cohesion tension mechanism

in the leaf, water is lost by ______ into the atmosphere

• Active transport

• Osmosis

• Transpiration

• Exocytosis

Negative pressure (tension) in the leaf xylem will create

• Transpirational push

• Transpirational pull

• Root pressure

• Guttation

The cohesion of water is due to

• Hydrogen bond between water molecule

• Adhesion between water molecule and wall of xylem

• Ionic bond

• Covalent bond

Root pressure is...

• Caused by transpiration at night

• Pushing force that push water upward only few meters

• Exudation of water from hydathodes

• caused by root cell absorbing mineral passively.

Source cell is

• A plant organ that produce CO2

• An organ that is a net consumer of sugar

• A plant organ that is net producer of sugar

• An organ that consume O2

An example of a sink cell is

• Companion cell

• Leaf

• Fruit

• Dead root

The movement of water and solutes through vessel and sieve tube by MASS FLOW is known as

• Pressure flow hypothesis

• Root pressure

• Transpiration cohesion tension mechanism

• Apoplast pathway
