In the Pressure-Flow mechanism to explain movement of phloem sap, is energy (ATP) being expended by the plant to move water? Is the plant expending ATP to move carbohydrates? Under what conditions? Why is it important that phloem be found typically in close association with xylem? A proton gradient can be established by cells in a root hair to bring nutrient cations and nutrient anions into the root cells against concentration gradients. How is the same process used in translocation? Where are the sugars provided by plants to mycorrhizal fungi produced? Where is the process at the top of Fig. \( 29.23 \) more than likely taking place? Why might the Casparian strip be more important in the presence of ectomycorrhizal fungal symbionts than in the presence of arbuscular mycorrhizal symbionts? Why would a plant be carnivorous/parasitic/epiphytic, from a nutritional standpoint? What conditions might result in these strategies? If a single air bubble forms within the xylem tissue, how would transpirational pull be affected? Can water still move up the xylem? There's a saying that you should cut flower stems you buy from the florist underwater. Why would that make a difference in how long the flowers persist in a vase? The character Groot from the Marvel Cinematic Universe. Hypothesize how Groot grows (i.e., does it have apical meristems? Vascular camblum?) Does the fact that it has a mouth make a difference? If you haven't seen the movies with Groot, spend a few minutes looking up clips of it])
