Answers A+ Graded (2025)




Chapter .36 .- .CORRECT .ANSWER--- .Resource .Acquisition .and .Transport .in
.Vascular .Plants


"materials" .required .for .life .- .CORRECT .ANSWER-nutrients

nutrition .in .all .organisms .involves .4 .main .steps .: .- .CORRECT .ANSWER--
.acquisition .of .nutrients
- .digestion, .if .required
- .distribution .of .nutrients .throughout .the .body
- .synthesis .of .molecules .for .the .organism's .body

starting .material .: .plants .- .CORRECT .ANSWER-elements .and .small .molecules

starting .material .: .animals .- .CORRECT .ANSWER-large .organic .molecules

digestion .: .plants .- .CORRECT .ANSWER-usually .none

digestion .: .animals .- .CORRECT .ANSWER-required .to .break .large .molecules
.down .to .building .blocks


distribution .: .plants .- .CORRECT .ANSWER-driven .by .osmosis .and .evaporation

distribution .: .animals .- .CORRECT .ANSWER-pumping .mechanism .for .most

synthesis .of .molecules .: .plants .- .CORRECT .ANSWER-can .do .it .all

synthesis .of .molecules .: .animals .- .CORRECT .ANSWER-must .acquire .through
.some .diet


plants .acquire .all .their .nutrients .from .: .- .CORRECT .ANSWER-- .soil .(minerals)
- .water
- .air

transport .in .vascular .pants .occurs .on .three .scales .: .- .CORRECT .ANSWER-1.
.transport .of .water .and .solutes .by .individual .cells

, 2. .short-distance .transport .of .substances .from .cell .to .cell .at .the .level .of .tissues
.and .organs
3. .long-distance .transport .(bulk .flow) .with .xylem .and .phloem

transport .of .water .and .solutes .by .individual .cells .occurs .via .- .CORRECT
.ANSWER-transmembrane .route


the .diffusion .of .free .water .across .a .membrane .- .CORRECT .ANSWER-osmosis

water .potential .(Ψ) .- .CORRECT .ANSWER-the .physical .property .that .predicts .the
.direction .in .which .water .will .flow


Water .potential .(Ψ) .is .affected .by .- .CORRECT .ANSWER-- .Solute .potential .(ΨS)
- .Pressure .potential .(ΨP)

solute .potential .(ΨS) .- .CORRECT .ANSWER-determined .by .concentration .of
.dissolved .molecules


pressure .potential .(ΨP) .- .CORRECT .ANSWER-determined .by .the .physical
.pressure .on .a .solution


water .potential .equation .- .CORRECT .ANSWER-Ψ .= .Ψs .+ .Ψp

water .moves .in .the .direction .where .the .water .potential .is .- .CORRECT .ANSWER-
lower

symplastic .route .- .CORRECT .ANSWER-allows .for .the .short-distance .transport
.of .substances .from .cell .to .cell .at .the .level .of .tissues .and .organs


symplastic .route .also .used .for .- .CORRECT .ANSWER-long-distance .transport
.(bulk .flow) .within .xylem .and .phloem


apoplastic .route .- .CORRECT .ANSWER-allows .movement .of .material .(water .and
.solute) .around .the .outside .of .cells .and .can .occur .over .long .distances .as .long
.as .no .barrier .to .the .route .exists


4 .step .process .of .mineral .absorption .by .roots .- .CORRECT .ANSWER-1. .active
.transport .into .root .hairs
2. .diffusion .through .root .hair .cytoplasm .to .endodermis .cells .vi .their .apoplastic
.or .symplastic .route
3. .active .transport .from .endodermis .cytoplasm .into .cell .or .the .extracellular
.space .of .the .vascular .cylinder
4. .diffusion .into .the .xylem

Casparian .strip .- .CORRECT .ANSWER-"leakproofs" .the .vascular .cylinder,
.retaining .the .concentrated .mineral .solution .within .the .extracellular .space .of .the
.vascular .cylinder
