The increase in the solute in the phloem increases the solute potential of the sieve tubes and creates a gradient that draws water into the cells from the adjacent xylem.
WebbCh. 36 Warm-Up Describe the process of how H2O gets into the plant and up to the leaves. Compare and contrast apoplastic flow to symplastic flow. Explain the mass flow of materials in the phloem (source to sink).
WebbPlasmodesmata (PD) play a key role in cargo of sugars into the phloem. In plant species that employ the so-called active symplasmic free strategy, succinic that diffused into their extraordinary intermediary cells (ICs) is converted into sugar oligomers.
