Summary Introduction
To review:
Whether the results were substantially similar or different for the two species used in the given experiment.
Introduction:
The transpiration process from leaves create negative pressure that helps to pull xylem sap upward. This is called cohesion–tension theory of water transport. It also takes place in the root system of the plant. The concentration of ions also influences the flow rate of water through xylem sap.

B) If you have a mesophyll cell in a leaf (a living, parenchyma cell in a leaf) with a slight positive
turgor pressure (Yp = 0.01 MPa) and solutes (Ys = -3.0 MPa), and it is next to a xylem vessel
element with very few solutes in the xylem sap (Ys = -0.01 MPa) but high physical tension (Yp
= - 2.0 MPa), which way will water flow?
a) from the mesophyll cell into the vessel element
b) from the vessel element into the mesophyll cell

- The following are some statements about long distance translocation of photo assimilates in higher plants: P. Sugars are translocated in the phloem by mass transfer along a hydrostatic pressure. Q. The translocated carbohydrates are mostly nonreducing sugars R. Munch pressure-flow hypothesis is crucial to drive translocation in the phloem S.

From what I understand, CO2 enters the stomata, and then the citric acid cycle of the mitochondia in the mesophyll use the carbon atoms do produce glucose, which then goes through phloem loading and it either used or stored. My question, I guess, is how exactly are the two types of mesophyll involved? Is only one used or are both used at different times in the production of the glucose?arrow_forwardImagine you have a plant with a water potential of -0.1 MPa in the root tissue. What would happen if you place the roots of this plant in a 0.1 M solution of sucrose (water potential is -0.23 MPa)? The net water flow would be from the tissue into the sucrose solution The net water flow would occur only as ATP was hydrolyzed in the tissue The net water flow would be from the sucrose solution into the tissue The net water flow would be in both directions and the concentration of water would remain equal The net water flow would be impossible to determine from the values given herearrow_forward

Which way does the water move?arrow_forwardBeans increase or decrease the turgidity of Pulvini cells to change the orientation of leaves. In order to raise the leaf blades to a horizontal position (as in the right side of the picture) pulvini cells at the junction between petiole and blade import sugar and potassium ions to increase their Yp from .30 Mpa to 0.67 Mpa. The pulvini cells are at equilibrium both before (leaf held more vertically) and after (leaf held horizontally) moving with an interstitial fluid that is not under pressure and has an unchanging osmotic potential of -3.31 Mpa. What is the osmotic potential of the Pulvini cell when the leaf blade is horizontal?arrow_forward(b) Water absorbed by plant roots travels by different pathways from the root hairs to the xylem.
