P
Second P
X
E
3
The transport of materials using a transport medium and pressure is known as:
The bohr theorem
Mass/pressure flow hypothesis
The unloaded passive hypothesis
The pressure theorem
4

True
False
5
Which statement is correct?
Translocation happens in the xylem and in the phloem
Transpiration happens in the xylem and translocation happens in the phloem
Transpiration happens in the xylem and in the phloem
Translocation happens in the xylem and the transpiration happens in the phl
6
During the night when transpiration rates are low, water can be forced out of the leaves by a process called...
unloaded passivity
Guttation
xylem
photosynthesis
7
Cohesion is the attraction between unlike molecules
True
False
8
Once sucrose reaches the sinks, the sucrose can only be converted to glucose for respiration
false
true
9
Sucrose moves via diffusion across the companion cell wall into the cytoplasm... (in apoplast)
True
False
10
Transport of sucrose is from...
Sources to sinks
Sinks to sources
11
Xylem tubes are...
Long cylinders made of living tissue with open ends
Long cylinders made solely of lignin with open ends
Long cylinders made of sap with open ends
Long cylinders made of dead tissue with open ends
12
Symplast...
Moves through the cell walls via root hair cells
Moves through the nucleus via plasmodesmata
Moves through the cytoplasm via root hair cells
Moves through the cytoplasm via plasmodesmata
13
What effect does wind speed have on transpiration?
Wind speed has no effect on the rate of transpiration
An increase in wind speed will lead to an increase in the rate of transpira
A decrease in wind speed results in an increase in the rate of transpiratio
14

True
False
16
Which of these are assimilates?
Amino Acids
Sucrose
All of the above
ATP

Moves through the cell walls and intracellular spaces which are permeable
Moves through the cell memb. and intercellular spaces which are permeable
Moves through the cell walls and intercellular spaces which are permeable
19
