Webb1 dec. 2014 · Plants transport the products of photosynthesis (food molecules) up and down the stem in phloem. The main carbohydrate transported is sucrose but phloem cells also contain lots of amino acids and a few other sugars. The mechanism by which these sugars are moved around the plant is less well understood than for water movement in … 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 When the stylets are withdrawn the stylet sheath remains in the tissues of the plant ... fithri syamsu https://tommyvadell.com
