Q. Stem is modified into cladode in

A) Casuarina
B) Asparagus
C) Opuntia
D) Euphorbia
Explanation

Cladode or cladophyll is typical phylloclade only one internode long. It develops by the modification of stem branches of limited growth and is green (photosynthetic). The tree leaves of the plant are reduced to scales in spines. In Asparagus, the cladodes are needle-like, slightly flattened, fleshy green structures developing in clusters in the axils of scale leaves. The main stem bears leaf spines at its nodes and the scale leaf occurs just above the spine.
