Which specific adaptation in the leaves of submerged hydrophytes contributes MOST significantly to their buoyancy and flexibility in water currents?
Highly dissected leaves
Absence of stomata
Presence of extensive aerenchyma
Thin cuticle
The bulliform cells in the leaves of certain grasses play a crucial role in:
Increasing the photosynthetic surface area.
Secreting resinous substances for protection.
Leaf rolling and unfolding in response to water availability.
