Phloem source to sink
WebbThe phloem and xylem are the main tissues responsible for this movement. Water potential, evapotranspiration, and stomatal regulation influence how water and nutrients are transported in plants. To understand how these processes work, we must first understand the energetics of water potential. Water Potential Webb3 apr. 2004 · The model has the following steps. Step 1: Sugar is loaded into the phloem tube from the sugar source, e.g. the leaf (active transport) Step 2: Water enters by …
