WebbPhloem loading is used variously to describe transport events outside, and inside, phloem tissues of leaves. The broader general application is adopted here — that is, phloem loading describes photoassimilate transport from the cytoplasm of photosynthetic mesophyll cells to se–cc complexes of leaf phloem. Webb5 dec. 2024 · Translocation through the phloem is dependent on metabolic activity of the phloem cells (in contrast to transport in the xylem). Chilling its petiole slows the rate at …

WebbAphids are small insects which feed by inserting their very fine mouthparts (stylets) into plant tissue, where they feed on cell sap (Fig. 1 A + B). As an aphid inserts its stylets into plant tissue it secretes a stylet sheath around the stylets (Fig. 2 A + B). When the stylets are withdrawn the stylet sheath remains in the tissues of the plant ... how does lisa rinna style her hairWebbPhloem sap is the term used to describe the organic matter that is transported through the phloem.
