Correct answer: C. Australian Acacia
- A. Asparagus
- B. Euphorbia
- C. Australian Acacia
- D. Opuntia
Explanation
(c) : In several species of Acacia found in the deserts of Australia the bipinnate lamina is absent. Instead petiole and part of the rachis become flattened into sickleshaped structure for performing the function of food synthesis. Such a flattened petiole which carries out the functions of the lamina is called phyllode. Formation of phyllode is a mechanism to reduce transpiration because (i) it is vertically placed and (ii) has fewer stomata.
