Summary Introduction
To Draw: A sketch of exchange of cations, a root hair, soil particle representing anion, and hydrogen ion displacing a cation.
Concept Introduction: The cations including K+, Ca2+, and Mg2+ adhere to soil particles because soil is negatively charged. This prevents the leaching out of cations out of the soil through percolating ground water. During exchange of cations, they are displaced by other cations from soil. Displaced cations then enter the soil solution and can be taken up by the plant roots.

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
c) neither direction. They are at equilibrium.

- Make a simple HAND DRAWN sketch or flow diagram toillustrate the flow path of water through a plant, from the point of uptake from the soil totranspiration from the leaves. Ensure that you incorporate the following aspects in your sketch / diagram:• Water movement from the soil into the root, to the vascular tissues and the rest of theplant and into the atmosphere.• Label all the organs, tissues and structures involved in water uptake and transport.• Mention the mode of water movement (e.g. diffusion, osmosis, mass flow) whereapplicable along the symplastic and apoplastic pathways of water uptake and transportarrow_forwardA leaf is placed in a beaker containing a salt solution with a solute potential of -0.5 MPa.

So I measure out 3 equal-sized squares of grass out the back of the Green Building. The first square of lawn I water with 5 liters of pure water from a watering can every day. The second square of lawn I water with 5 liters of pure water with 2 grams of salt mixed in, every day. The third square of lawn I water with 5 liters of pure water with 4 grams of salt mixed in, every day. I measure the height of the grass after 14 days and note the following observations. The first square is green and 15 cm high. The second square is greeny-yellow and 6 cm high. The third square is yellowy-brown and looks dead and is only 2cm high. What could we infer about the effect salt has on the growth of grass?arrow_forward
