- Given that (a) xylem is located toward the upper epidermis in leaf veins and phloem is located toward the lower epidermis and (b) the vascular tissue of a leaf is continuous with that of the stem, suggest one possible arrangement of vascular tissues in the stem that might account for the arrangement of vascular tissue in the leaf.Water ascent up a plant is vital for maintaining proper physiological function of the leaves, (a) is root pressure or the cohesion-tension theory MORE important in supplying water to the leaf? (b) explain the difference in the driving force of water ascent between root pressure and cohesion tension.A) The concentration of CO2 is lower inside a plant cell than in the atmosphere (outside the cell). In your own words, describe how the CO2 levels are kept low inside the plant cell and explain why this is necessary. Assume stomata are open. B) Regarding the situation presented in Part A and assuming that the stomata of the plant leaves are closed, would this favour the induction of photorespiration in a C3 plant? Explain. Make reference to relevant molecule or molecules as needed. Please clearly label your responses as A and B

(You place a flaccid plant cell (Ψ = -0.7 MPa) into an environment (beaker) of pure (deionized) water (Ψ = 0 MPa). Compare the initial conditions of the flaccid cell and the environment (beaker of pure water) in terms of: G) Predict the direction of water movement (into the cell, out of the cell, or no net movement) H) Predict the change in turgor pressor of the cell (increase turgor pressure or decrease turgor pressure) I) Predict the fate of the cell (plasmolyzed, turgid, or lysed)
