NEET Questions / Botany / Anatomy of Flowering Plants / Monocot Leaf
In a monocot leaf, the bulliform cells are primarily responsible for which of the following adaptations?
Increasing the surface area for photosynthesis
Providing structural support to the leaf blade
Storing water for use during drought conditions
Rolling of the leaf during water stress
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.
If a grass plant's leaves are observed to be curled inwards, what can be inferred about the environmental conditions?
The environment is excessively humid
The environment has high salinity
The environment is experiencing strong winds
The environment is likely dry or arid
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
I. Sunflower seed
II. A wheat leaf
III. Pea plant
IV. Leaf blade of grass
Bulliform cells are present in which of the above plants?
I and II
II and IV
III and IV
I and III
