Students have asked these similar questions
In order to increase nutrient uptake, plant roots will often exude ____ ions into the soil, which will tend to ____ the pH of the soil.
Select one:
a.
H+, increase
b.
OH-, increase
c.
H+, decrease
d.
OH-, decrease
Select all that are true regarding soil
a.
the most abundant element of soil is inorganic mater
b.
plants passively acquire cations by using ATP to pump H+ into the soil
c.
soil plays key roles in water regulation and buffering of pollutants
d.
soil is an essential source of carbon for plants
e.
plants use H+ from photosynthesis to acquire cations
f.
anions are unbound in the soil and freely travel into plant roots with water
g.
cation exchange is required because cations are bound to negatively charged soil particles
h.
H+ works well for the cation exchange because it is a small molecule with a strong charge
2. Select all that apply to plant nutrition
a.
green manure can restore minerals to soil but is to expensive for farmers to use
b.
mineral deficiencies cause symptoms like chlorosis, a browning and death of plant tissue
c.
fertilizers typically contain nitrogen, potassium, and phosphorus,…
Which of the following would allow a plant to tolerate a cold environment?
Group of answer choices
A. producing small, smooth leaves with a small boundary layer
B. generating sparsely placed leaf hairs to reflect solar radiation
C. increasing the proportion of unsaturated fatty acids in cell membranes
D. increasing evapotranspiration
E. increasing the proportion of leaf mass relative to total body mass
