NEET Questions / Botany / Anatomy of Flowering Plants / Monocot Leaf
In certain monocot species adapted to arid environments, the presence of a thick cuticle and sunken stomata are crucial adaptations. Relate these features to the overall function of the monocot leaf in such environments.
They enhance light absorption for increased photosynthetic rates.
They provide structural support to withstand strong winds.
They minimize water loss while maintaining essential gas exchange for photosynthesis.
They store excess water for use during periods of drought.
Bulliform cells in monocot leaves are responsible for:
Photosynthesis
Transpiration
Storage of water
Rolling and unrolling of leaves
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
The inward curling of leaves in grasses during dry periods is an example of:
A hydromorphic adaptation
A mesomorphic adaptation
A halomorphic adaptation
A xeromorphic adaptation
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
The presence of bulliform cells on the upper epidermis of grass leaves allows for:
Increased photosynthetic rate
Enhanced nutrient absorption
Minimizing water loss during dry conditions
Providing structural support to the leaf
Under which environmental condition would bulliform cells be most likely to cause a grass leaf to roll inwards?
High humidity
Low light intensity
Cold temperatures
Hot, dry conditions
