A cell placed in a hypotonic solution will:
Swell
Shrink
Stay the same
Burst immediately
Root pressure is typically highest under which of the following conditions?
High soil moisture and high transpiration rate
Low soil moisture and low transpiration rate
Low soil moisture and high transpiration rate
High soil moisture and low transpiration rate
Guttation, the exudation of water droplets from leaves, is most likely to occur when:
Root pressure is low and transpiration is high.
Root pressure is high and transpiration is high.
Root pressure is low and transpiration is low.
Root pressure is high and transpiration is low.
Which of the following adaptations helps reduce transpiration in xerophytes?
Large, thin leaves
Sunken stomata
Numerous stomata on the upper leaf surface
Thin cuticle
A plant is exposed to high light intensity and limited water availability. Which of the following is the most likely physiological response?
Increased stomatal opening to maximize CO2 uptake for photosynthesis.
No change in stomatal aperture, maintaining a balance between transpiration and photosynthesis.
Complete closure of stomata to prevent water loss, halting photosynthesis.
Partial closure of stomata to reduce transpiration, even at the cost of reduced CO2 uptake for photosynthesis.
Which adaptation is LEAST likely to be found in plants adapted to arid environments?
Sunken stomata
Thick cuticle
Large, thin leaves
Succulence
The transpiration-photosynthesis compromise is most pronounced in which type of environment?
Cool and humid
Hot and humid
Hot and dry
Cool and dry
On a hot, dry day, a plant is most likely to:
Open its stomata fully to maximize photosynthesis.
Partially close its stomata to conserve water, even though this reduces photosynthesis.
Completely close its stomata to prevent any water loss.
Increase its rate of photosynthesis to compensate for water loss.
A cell with a water potential of -0.2 MPa is placed in a solution with a water potential of -0.4 MPa. Which of the following will occur?
Water will move into the cell.
Water will move out of the cell.
There will be no net movement of water.
The cell will burst.
Which of the following best describes the effect of placing a red blood cell in a hypotonic solution?
The cell will shrink.
The cell will swell and may burst.
The cell will remain unchanged.
The cell will undergo plasmolysis.
