Значение термина mass flow в knolik
mass flow - mass flow
mass flow - Hypothesis of transport of materials in phloem. Sieve-tubes and contents are regarded as forming an osmotic system continuous throughout the plant connected, via plasmo-desmata, with other tissues. A gradient of osmotic and hence turgor pressure exists within the sieve-tube system as a result of entry into it of synthesized materials, e.g. sugars, from the leaf mesophyll (increasing pressures), and their removal for consumption in areas of growth and storage (lowering pressures). This pressure gradient results in mass flow of water and dissolved substances through the system from regions of high to regions of low pressure. Circulation of water is completed via the xylem with which the phloem is intimately connected.
