The transpiration and photosynthesis compromise is primarily a balance between:
Oxygen production and CO2 uptake
Sugar production and water uptake
CO2 uptake and water loss
Light absorption and sugar production
Which of the following best describes the transpiration and photosynthesis compromise?
Plants prioritize transpiration over photosynthesis in hot conditions.
Photosynthesis always takes precedence over transpiration.
Plants must balance the need to take in CO2 for photosynthesis with the risk of water loss through stomata.
Transpiration and photosynthesis are unrelated processes.
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 of the following environmental factors would MOST directly influence the transpiration-photosynthesis compromise?
Light intensity
Air humidity
CO2 concentration
Soil nutrient availability
A researcher observes that a plant species exhibits a lower transpiration rate and higher water use efficiency (WUE) under high light intensity compared to low light. Which physiological adaptation BEST explains this observation?
Increased leaf thickness
Deeper root system
Increased chlorophyll content
Partial stomatal closure
Under conditions of high temperature and low humidity, which factor MOST directly exacerbates the transpiration and photosynthesis compromise?
Decreased CO2 concentration
Increased vapor pressure deficit
Reduced soil water potential
Elevated atmospheric pressure
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.
If a plant's stomata are completely closed, which of the following would be the most immediate consequence?
Increased transpiration
No CO2 uptake and cessation of photosynthesis
Increased water uptake by roots
Wilting of leaves
