Question

Acacia arabica is a

• A. Mesophyte
• B. Hydrophyte
• C. Xerophyte
• D. Halophyte

Answer 1

The correct option is C Xerophyte

Xerophytes are plants of dry habitats, where the environment favours higher rate of transpiration than the absorption. In these plants leaves are small and vestigial to cut transpiration. Lamina is vestigial, while petiole enlarges to form phyllode in australian species of Acacia. Phyllode refers to flattened petiole, which is green and photosynthetic.

So, the correct answer is 'Xerophyte'
