Prepare for NEET with Botany-specific practice questions. Covering all major Botany chapters, this is perfect for your NEET Biology needs.
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
Guttation is the process responsible for the loss of water in liquid form from the tips of grass blades. Under what environmental conditions is guttation most likely to occur?
High temperature and low humidity
High temperature and high humidity
High humidity and low temperature
Low humidity and low temperature
Which process, unlike transpiration, results in the loss of water in liquid form from plants?
Evaporation
Transpiration
Guttation
Condensation
During periods of extreme dryness, the leaves of grasses often curl inwards. What is the primary reason for this adaptation?
To increase sunlight absorption
To protect against herbivores
To trap more carbon dioxide
To minimize water loss through transpiration
Which of the following best explains why grass leaves curl inwards under drought conditions?
Increased sunlight reflection
Enhanced carbon dioxide uptake
Protection from insect damage
Reduction of transpiration rate
How does the inward curling of leaves benefit grasses in arid environments?
Increases light absorption for photosynthesis
Improves nutrient uptake from the soil
Protects against herbivore grazing
Reduces water loss through transpiration
Which of the following factors does NOT directly influence the opening and closing of stomata?
Light intensity
Carbon dioxide concentration
Water availability
Temperature
