DP Biology Vocabulary - 9.2 Transport in the phloem of plants
Essential vocabulary for the IBO DP Biology course
Terms in this set (6)
a transport mechanism where ions or molecules move against a concentration gradient, this movement requires energy.
Hydrostatic pressure gradient
the stress that develops when solutions containing different concentrations of solute in a common solvent are separated by a membrane that is permeable to the solvent, but not the solute.
Incompressibility of water
the incapability of water to lose volume in response to pressure.
the diffusion of fluid through a semi-permeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal concentration of fluid on both sides of the membrane.
the food-conducting tissue of vascular plants that conducts synthesized nutrients to different parts of the plants.
an element of phloem tissue consisting of a longitudinal row of thin-walled elongated cells with perforations in their connecting walls through which food materials pass.
