Difficulty: EasyMorphological and Physiological Adaptations to Environments

Xerophytic plants typically possess a thick waxy cuticle on their leaf surfaces as a morphological adaptation to minimize cuticular transpiration in arid environments.

Answer: Answer

Answer

The statement is true because a thick waxy cuticle provides an impermeable physical barrier on the leaf epidermis, reducing non-stomatal water loss in plants adapted to dry habitats.
The statement is true because xerophytic plants possess a thick, waxy cuticle over their leaf surfaces specifically to cut down on cuticular water loss and endure prolonged periods of dry conditions.

Step-by-Step Solution

1
Identify the ecological group and environment described.
The organism is a xerophyte, which lives in arid or drought-prone environments.
Environmental conditions determine the survival pressures acting on the organism.
2
Analyze the function of the thick waxy cuticle.
Wax is hydrophobic and prevents water movement across the epidermal cell layer.
Structural features that limit evaporation conserve limited internal water reserves.
3
Conclude whether this represents an authentic morphological adaptation.
Reducing cuticular transpiration via a thick waxy cuticle is a confirmed morphological adaptation in xerophytic plants.
The factual claim in the statement is fully correct.
