Phloem tubes definition
WebbXylem and phloem together make the vascular bundle in plants. 1. Xylem: The cells have thick cell wall and many of them are dead. This tissue helps in the transport of water and dissolved substances throughout the plant. The different components of the xylem include tracheids, vessels, xylem parenchyma and xylem fibres. WebbPhloem is one of the two tissues that make up the plant's long-distance transport system, the other being xylem. Phloem translocates water and products of photosynthesis from source tissues to the sink regions where they are utilized or stored. Primary phloem originates from the procambial regions in meristems, while secondary phloem originates ...

WebbIn vascular plants, phloem is the living tissue made up of small tubes which carry watery sap containing sugar and other organic nutrients to all parts of the plant where the nutrients are used for growth, or stored until needed. The sugar is made by photosynthesis. WebbThe current–voltage curves depicted in (A) demonstrate that in contrast to fou2 and ouf8, the wild-type TPC1 outward currents, reflecting K + uptake into the vacuole, are suppressed at high vacuolar Ca 2+ loads. Contrary to fou2 (D454N), the ability to release luminal K + into the cytosol via TPC1 channels (B) is impaired in the TPC1 pore-channel mutant ouf8 …
