Transport process
Diffusion, Osmosis and Active transport
Osmosis
Water moving from high to low concentration
Diffusion
Random movements from high to low concentration particles
Active Transport
Force of energy through membrane
Water Potential
Pressure potential
Osmotic potential
Matrix potential
Water and cell movement
Incident plasmosis
Plasmolized
Short distance intercellular transport
Symplast
Apoplast
Guard cell
Motor cell
Transport cell
Long distance Transport
Phloem
Pressure flow hypothesis
Increases osmotic concentration, decreases water potential in sieve tube
Water enters sieve tube from xylem due to water potential differential, creating turgor pressure
Assimilate loaded into sieve tube elements with help of companion cells from source
Xylem
Water enters through root hair via osmosis
Water evaporates out of open stomata
Water pases through endodermis,
Water potential gradient from mesophyll cells
Water pulled up stem under tension
Water remains unbroken due to cohesion of water molecules
