TURF 435 QUIZ 1 QUESTIONS & ANSWERS
A portion of a plant cell is shown below, complete with a nucleus, cell membrane, and
carrier protein (green). Examine the green carrier protein and please choose the more
specific characterization from the choices shown. - Answer -Symport carrier protein
The green carrier protein has been signaled to assimilate a phosphate (H2PO4-) ion. To
do so, it will most likely engage in which type of diffusion or transport? - Answer -
Facilitated Diffusion
The green carrier protein (shown in the figure below) will most likely co-transport which
ion to facilitate uptake of the desired phosphate (H2PO4-) ion? - Answer -H+
Do the two steps shown above illustrate plant nutrient uptake (a.k.a. assimilation) by a
carrier protein? - Answer -Yes
The green carrier protein has assimilated two phosphate ions, yet is being signalled to
absorb as many as possible. Will it continue to use the hydrogen ions (H+) as
cotransport cations for passive uptake of the desired phosphate ion? - Answer -No, it
will use sodium (Na+)
The green symport carrier protein has now assimilated four phosphate ions, yet will
continue absorbing as many as possible. Which type of uptake will be necessary to
assimilate the fifth phosphate ion? - Answer -Active Transport
OK, while you were answering the last question, some things have changed. Namely,
several more ions have diffused 'up against' the exterior of the cell membrane. You can
now predict assimilation of the fifth phosphate ion will occur by facilitated diffusion , and
the carrier protein will employ Hydrogen (H+) as the cotransport ion. - Answer -
FacilitatedDiffusion
H+
Which of the following is true about foliar fertilization of turfgrass systems? - Answer -
Foliar fertilization can be a useful turfgrass management tool under certain
circumstances; but apart from those, is nothing extraordinary or magical.
Relative to the application of granular fertilizers, foliar fertilization is likely to: - Answer -
more rapidly rectify existing nutrient deficiencies of turfgrass systems
Which of the following events best qualifies as foliar fertilization? - Answer -Two hours
after fairways are mowed, spray-application of a contact fungicide + ammonium nitrate
tank mix in a 75 gallon-per-acre (GPA) carrier volume.
