Prepare for NEET with Botany-specific practice questions. Covering all major Botany chapters, this is perfect for your NEET Biology needs.
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
Conifers thrive in challenging environments due to:
Thick bark, needle-like leaves, and sunken stomata
Broad leaves, shallow roots, and prominent stomata
Thin bark, large leaves, and exposed stomata
Soft stems, feathery leaves, and numerous stomata
Which adaptation helps conifers reduce water loss in arid environments?
Broad leaves
Needle-like leaves
Shallow roots
Thick bark
How does the conical shape of many conifers benefit them in snowy regions?
It increases sunlight absorption.
It helps shed snow, preventing branch breakage.
It attracts pollinators.
It provides camouflage from herbivores.
The sunken stomata in conifers primarily contribute to:
Increased sunlight absorption
Enhanced gas exchange
Reduced water loss
Improved nutrient uptake
