Phloem Definition & Meaning - Merriam-Webster
WebbOrganic compounds are transported from sources to sinks via a vascular tube system called the phloem Sugars are principally transported as sucrose (disaccharide), because it is soluble but metabolically inert The nutrient-rich, viscous fluid of the phloem is called plant sap Active Translocation WebbThey may be components of the xylem and/or phloem or may occur independently of vascular tissue. Sclereids may also function in structural support, but their role in some plant organs is unclear; they may possibly help to deter herbivory in some plants. sedge picture

WebbCitrus tristeza virus (CTV) is phloem restricted in natural citrus hosts.The 23‐kDa protein (p23) encoded by the virus is an RNA silencing suppressor and a pathogenicity determinant. The expression of p23, or its N ‐terminal 157‐amino‐acid fragment comprising the zinc finger and flanking basic motifs, driven by the constitutive 35S promoter of … WebbWater potential and transpiration influence how water is transported through the xylem in plants. These processes are regulated by stomatal opening and closing. Photosynthates (mainly sucrose) move from sources to sinks through the plant’s phloem. Sucrose is actively loaded into the sieve-tube elements of the phloem.
