transport process
active transport
-
there are secondary active transport processes similar to diffusion but instead use imbalances in electrostatic forces to move molecules across the membrane. #
happens over a semipermeable film against the typical fixation angle, moving from the zone of lower focus to the region of higher fixation and requiring a use of vitality discharged from an ATP atom
-
Diffusion
movement of molecules from high concentration to low concentration and vice versa until it reaches the equlibirum stages.
diffusion rate depends on the mass and temperature of the molecule; lighter and warmer molecules move faster

-
osmosis
movement of water or other solvent through plasma membrane from region of low concentration to high concentration.
-
long distant transport
xylem
-
found on n roots, stems and leaves of the plant #
function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients
pholem
cells in the phloem need to be alive to provide energy for active transport when transporting sucrose around the plant.
-
Phloem parenchyma cells, called transfer cells and border parenchyma cells located near the finest branches and terminations of sieve tubes in leaf veinlets, where they also function in the transport of foods.
found on root, stem and plants
