Root pressure is primarily responsible for which of the following?
Transpiration
Wilting
Guttation
Photosynthesis
Which of the following BEST explains why the ascent of sap in tall trees is primarily attributed to the cohesion-tension theory rather than root pressure?
Root pressure only operates during the night
Root pressure is primarily involved in nutrient transport, not water transport
Root pressure alone cannot generate sufficient pressure to overcome the gravitational force in tall trees
The cohesion-tension theory is more energy-efficient than root pressure
Which of the following is the main driving force for root pressure?
Transpiration pull
Active transport of ions into the xylem
Capillary action in the xylem vessels
Photosynthesis in the leaves
Root pressure is most likely to be observed in which of the following conditions?
High temperature and high transpiration
High humidity and low transpiration
Strong winds and high light intensity
Dry soil and low humidity
Which phenomenon demonstrates the existence of root pressure?
Transpiration
Wilting
Guttation
Photosynthesis
Root pressure primarily contributes to the movement of water in:
Tall trees
Short plants and herbs
Desert plants
Submerged aquatic plants
The structure through which water is exuded during guttation is called:
Stomata
Lenticels
Hydathodes
Trichomes
Which of the following processes explains the appearance of water droplets on the margins of leaves of a small herbaceous plant during a humid night?
Transpiration
Respiration
Guttation
Photosynthesis
