10 cards from this deck
Movement of dissolved photosynthetic assimilates through plant
Sucrose
Soluble, chemically unreactive, less effect on water potential
Region with high sucrose concentration
Area requiring sugar, with low sucrose concentration
Sucrose accumulates above ring, can't pass - proves phloem needed
Pressure-driven bulk flow of solution through sieve tube elements
Provide ATP for active transport of sucrose into sieve tubes
Sucrose loaded, lowers water potential, water enters by osmosis
High pressure at source, lower pressure at sink drives mass flow
