(e)quantity of mutants available
2.Indeterminate growth of higher plants is due to
(a)tip growth of cells (b)apical meristem (c)evergree leaves (d)formation of
lateral roots (e)occurrence of adventitious buds
3.Functions of Golgi apparatus
(a)protein synthesis (b)O-linked glycosylation of proteins (c)forming traffic
vesicles (d)synthesizing cellulose (e)synthesizing non-cellulosic
polysaccharides of cell wall
4.Oraganells surrounded by double membrance
(a)polyribosomes (b)mitochondrion (c)peroxisome (d)chromoplast (e)oleosome
5.Which one is nothing todo with cell division
(a)preprophase band (b)phragmoplast (c)mitotic cyclins (d)cytoplasmic
streaming (e)kinetochore microtubule
6.Properties of Aquaporin
(a)potassium channel (b)peripheral membrance protein (c)intrinsic membrance
protein (d)water channel (e)can hydrolyze ATP
7.When a plant cell having -0.635 MPa of water potential was soaked in 0.3M
mannitol solution for 5 minutes, and then transferred to 0.4M sucrose solution
(R:0.008314 MPa mol-1 K-1)
(a)the cell absorbed water in the first solution, and lost water in the
second solution
(b)the cell lost water in the first solution andgained water in the second
solution
(c)the cell lost water in the first solution and lost more water in the second
solution
(d)the cell lostno water in the first solution(gain no water either), but lost
water in the second solution
(e)the cell lost water in the first solution, and absorded no water in the
second solution
8.Pick up the true statements about an active cell
(a)its pressure potential is maintained negative in order to absorb water
(b)its osmotic potential approaches to zero when the cell is at steady state
in distilled water
(c)its water potential is approaching zero when soaked in distilled water
(d)its matric potential contributes a lot to the water absorption
(e)its water potential always maintains negative even soaking in pure water
for an hour
9.the sensitivity of physiological phenomena to the changes of cell water
status
(a)cell expansion > photosynthesis > protein synthesis
(b)leaf wilting > cell expansion > photosynthesis
(c)protein synthesisi > cell expansion > ABA accumulation
(d)cell expansion > stomatal closure > ABA accumulation
(e)cell expansion > ABA accumulation > stomatal closure
10.Menbrance potential of plant cells have two components:a diffusion
potential (generated from the diffusion of charged ions) and potential
resulted from electrogenic transport.Unequal amount of oppositely charged-ion
movement across cell membrance generates an electric potential across the
membrance, __ pump is the most important transport in plant cell.By that the
outward transport of __ can create a driving force for the passive diffusion
of K+ into the cell.The addition of CN- blocks the production of __, and
lowers the membrance potential that in turn __ K+ transport
(a)H+-ATP,proton,proton,reduce (b)H+-ATP,proton,ATP,reduce
(c)H+-ATP,K+,ATP,enchance (d)H+-ATP,Ca2+,ATP,enchance (e)proton,K+,ATP,enchanc
11.Which statement is not correct in water culture(hydroponics)
(a)the concentration of minerals in culture solution is usually much higher
than thatin soil water (b)chelating agents are added into solution in order to
prevent ions from precipitation (c)antibiotics is included for preventing
microbe contamination (d)aeration is needed for normal growth of root system
(e)pH stability is required for healty growth
12.Diffusion of water vapor from leaf to the atmosphere is driven by
(a)the difference if relative humidity between the leaf interior and the air
(b)thedifferience of water vapor concentration between the air and leaf
interior
(c)the temperature difference between leaf and air
(d)the water potential difference between mesophyll cell and atmosphere
(e)the pressure gradient between leaf interior ant atmosphere
13.A well-watered plant performs higner transpiration in windy day than in
windless day,because
(a)stomata aperture is larger in the windy day (b)stomata close in the windy
day (c)resistance of boundary layer is much lower in the moving air (d)
conductivity of stomata is higher in the moving air (e)transpiration pull is
stronger in the windy day
