TURF 435 QUIZ 1 QUESTIONS WITH CORRECT ANSWERS LATEST UPDATE 2025-2026
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. - Answers 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? - Answers 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? - Answers H+
Do the two steps shown above illustrate plant nutrient uptake (a.k.a. assimilation) by a carrier
protein? - Answers 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? - Answers 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? - Answers 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. - Answers FacilitatedDiffusion
H+
Which of the following is true about foliar fertilization of turfgrass systems? - Answers 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: - Answers more
rapidly rectify existing nutrient deficiencies of turfgrass systems
Which of the following events best qualifies as foliar fertilization? - Answers 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.
Which of the following types of plant nutrient acquisition is not limited to the turfgrass plant; i.e.,
involves at least one other organism? - Answers Biological Transport
