Transport Processes
Methods of transport Processes
Diffusion
Movement of particles from higher concentration to lower concentration until equilibrium is reached
Aquaporins
Protein channels
Active Transport
Movement of ions or molecules from lower to higher concentration with the consumption of energy
Intracellular transport
vesciles migrate through cytoplasm
Osmosis
Presence of semi-permeable membrane allows the solvent molecules to be free to move to equalize concentration
Long distance transport-Phloem
Pressure flow hypothesis
P-Protein
network adjacent to plasma membrane
Callose
Polymer within uninjured phloem
specific mass transfer
Mass transfer
Sinks
Transported phloem sap
Water Potential
Cells and Water movement
capacity of doing work
Free energy
Potentials
Osmotic potential
Matric potential
Pressure potential
Short distance Intercellular Transport
Motor Cells
:
Transfer Cells
Guard Cells
regulate CO2 influx from the atmosphere into the leaves for photosynthetic carbon fixation
regulate water loss of plants via transpiration to the atmosphere.
Symplast
Apoplast
Long distance Transport- Xylem
