Web-Two major functions of vascular tissue are to facilitate the transport of materials through the plant and to provide mechanical support. There are two types of vascular tissue: xylem and phloem. o Xylem conducts water and dissolved minerals upward from roots into shoots. o Phloem transports sugars from the leaves and into roots or sites of growth. WebAt the sink, the companion cells actively transport sucrose out of the phloem into the cells that need the sucrose. Removing sucrose from the phloem tubes reduces the …

How Plants Send Sugars from Sources to Sinks - dummies

WebThe phloem moves food substances that the plant has produced by photosynthesis to where they are needed for processes such as: growing parts of the plant for immediate use … WebPhloem is vascular tissue that moves food throughout the plant. It does this through a series of tubes that connect sugar sources (such as leaves) to sugar sinks (such as growing fruits, stems and roots). The pressure flow hypothesis helps explain how dissolved sugars move from sugar sources to sugar sinks. How does the stem transport water? northlands wood chemist
