試題 :
14.transpiration can efficiently decrease plant body temperature because
(a)high latent heat of water (b)high thermal conductivity of water (c)high
fusion heat of water (d)hogh melting point of water (e)high boiling point of
water
15.Transpiration ration (TR) is an important trait of plant species in an
ecosystem
(a)plant having higher TR can use water more efficient
(b)plant with lower TR can use water more efficiently
(c)C4 plants usually have higher TR, so they can survive in arid area better
than C3 plants
(d)CAM plants have lower TR than C3 palnts, so they growth faster than C3
plants
(e)plants having higher TR can stand more drought stress
16.The microelement essential for plant growth are (in the order of the
quantity in tissue)
(a)Ni,Mo,Cu,Zn,Na,Mn,B,Fe,Cl (b)Ni,Mo,Cu,Na,Zn,Mn,B,Cl,Fe
(c)Mo,Ni,Na,Cu,Zn,Mn,B,Fe,Cl (d)Mo,Ni.Cu,Na,Zn,B,Mn,Fe.Cl
(e)Mo.Ni.Cu.Zn.Na.Mn.B.Fe.Cl
17.The most apparent deficiency symptom of essential elements:
(a)early flowering (b)formation of anthocyanin (c)necrosis (d)chlorosis
(e)wilting
18.The deficiency symptoms appear in young tissue even the meristem
(a)Fe.B.Ca.K (b)P.Ca.Mg.Mn (c)Mn.Fe.P.Ca (d)Cu.Cl.Fe.Ca (e)Cu.Ca.Fe.B
19.Which fertilization gives the prompt improvement of the deficiency problem?
(a)foliar application of organic fertilizer (b)foliar application of chemical
fertilizer (c)drip application of chemical fertilizer (d)drip application of
organic fertilizer (e)flooding with a quantity of water enriched with
chemical fertilizer
20.Mycorrhiza is an association of fungi with plant root. The association
relationship usually benefits both organisms.
(a)fungi and plants always take the same extent of advantages under any soil
conditions
(b)plants gain more advantahe than fungi when the soil fertility is high
(c)plants take more advantages when the soil is arid and poor
(d)fungi take more advantages when the soil fertility is high
(e)palnts take more adventages since mycorrhizal fungi serve as organic
nutrient for plants
21.The true statement regarding xylem loading is:
(a)xylem loading of ions is definitely passive because vessels are dead
(b)xylem loading is may be active since the loading is down the
electrochemical potential
(c)xylem loading is active since its loading rate is higher during
photosynthesis
(d)H+-ATPase and efflux channels are mainly responsible for active xylem
loading
(e)H+-ATPase and influx channels are mainly reponsivle for xylem loading
22.which following data not support the occurrence of apoplastic loading
(a)transgenic plants over expressing wall invertase reduces the phloem
loading and decreases in growth
(b)transported sugars are found in apoplast
(c)PCMBS inhibits loading
(d)exogenous supply of sucrose is accumulated in sieve elements and companion
cells
(e)rich in plasmodesmata between sieve element and phloem parenchyma cell
23.polymer trapping model was proposed to interpret the following
physiological action
(a)aquaporins facilitate the water absorption (b)symplastic pathway of phloem
loading (c)symplastic pathway of xylem loading (d)apoplastic pathway of phloem
loading (e)apoplastic pathway of xylem loading
24.When sink organs are removed and photosynthesisi rate in source leaves
usually reduces. Some other physiological phenomena are also observed,expect
(a)increase sucrose in the source (b)high sucrose in vascular tissue (c)
down-regulation of H+-sucrose antiporter in the source leaves (d)
down-regulation of H+-sucrose synportwe in source leaves (e)decrease loading
in the source tissue
25.the sink strength of vatious organs is quite different, which following
organ has the strongest sink strength
(a)the growing cambium (b)a developing leaf (c)a growing fruit (d)an opning
flower (e)a sprouting branch
Essay:(pick 5 questions from 7; 10 points for each question)
1.Discuss factors affecting/determining the rate of water uptake by a root.
(driving force,resistance...)
2.Explanin why transpiration contribute to the water ascent in plant body.
3.Compare the characteristics of V-type ATPase and P-type ATPase
4.Compare the properties of channels and carrier.
5.Decribe the relationships of phloem loading ant the type of companion cells.
6.Give examples to explain the primary active transport and the secondary
active transport.
7.Describe the pattern of sink-source transition of a developing leaf.
