Match each organism or plant group with its characteristic morphological or physiological adaptation to its environmental habitat.
- Floating Hydrophyte (e.g., Nymphaea)Stomata restricted strictly to the upper leaf epidermis (epistomatous) paired with extensive air spaces (aerenchyma).
- Halophytic Mangrove (e.g., Avicennia)Negatively geotropic breathing roots (pneumatophores) bearing lenticels for gaseous exchange in anaerobic mud.
- Desert Mammal (e.g., Camelus)Physiological tolerance to elevated body temperatures (hyperthermia) and production of hypertonic, concentrated urine.
- Xerophytic Succulent (e.g., Opuntia)Flattened photosynthetic stems (cladodes) with leaves reduced to non-transpiring protective spines.
Answer
Floating Hydrophyte matches epistomatous leaves with extensive aerenchyma; Halophytic Mangrove matches negatively geotropic pneumatophores with lenticels; Desert Mammal matches hyperthermia tolerance and hypertonic urine production; Xerophytic Succulent matches photosynthetic cladodes with leaf spines.
Each organism is accurately paired with its primary adaptation: floating hydrophytes rely on upper-surface stomata and aerenchyma for buoyancy and gas exchange; mangroves utilize pneumatophores with lenticels to overcome root hypoxia in mud; desert mammals regulate water loss through hyperthermia tolerance and hypertonic urine; and cacti minimize transpiration via leaf spines while storing water in photosynthetic cladodes.
Step-by-Step Solution
Key Concept
Morphological and physiological adaptations represent structural and functional modifications enabling organisms to overcome specific environmental stresses across aquatic, saline, and arid habitats.
