What do cladodes do?
Cladodes (also called cladophylls or phylloclades) are shoot systems in which leaves do not develop; rather, the stems become flattened and assume the photosynthetic functions of the plant. In asparagus (Asparagus officinalis; Asparagaceae), the scales found on the asparagus spears are the true leaves.
What is cladode give example?
Cladode is a form of modified stem, which is green and fleshy in nature. The leaves are modified to form spines. The cladode arises from the axil of these leaves. There are many examples of plants in which there are stem modified to form cladode like Euphorbia tirucalli and Euphorbia antiquorum.
What is meant by a phylloclade?
Definition of phylloclade : a flattened stem or branch (such as a joint of a cactus) that functions as a leaf.
What is phyllode Phylloclade and Cladode?
A phylloclade is a flattened stem of with multiple internodes and nodes that serve as a leaf. It arise in the axil of the leaf, does not have any axillary bud but shows unlimited growth. A cladode is defined as a phylloclade of one or two internodes.
What is cactus phylloclade?
Phylloclades are flattened shoots and are considered as modified branches. They are flattened leaf-like branches and structures that are photosynthetic in nature. In Cactus, the phylloclade is flattened, reduced or gets modified as spines.
Is Opuntia a cladode or phylloclade?
The phylloclade stem becomes leafy and fleshy. It is a commonly occurring condition in opuntia. Cladode is a type of modified stem . It is fleshy and green in nature .
Is Opuntia a cladode?
Opuntia species are fast-growing perennial succulents with thickened, often flattened, segmented cladodes, usually supporting spines. Most Opuntia will regenerate from seed, cladode fragments, and underground tubers.
Is Opuntia a phyllode?
In some plants, these become flattened and widened, while the leaf itself becomes reduced or vanishes altogether. Thus the phyllode comes to serve the purpose of the leaf. Some important examples are Euphorbia royleana which are cylindrical and Opuntia which are flattened.
Is Opuntia a phylloclade?
Phylloclade is also a type of stem modification where the flattened leaf-like structures are formed, which helps in photosynthesis, examples are cactus opuntia.

What is phylloclade Class 11?
Phylloclade is a special modified photosynthetic stem present mostly in xerophytes. They have a reduction in leaf size, early leaf fall, the formation of scaly leaves, spine, thorns, cuticle etc to reduce transpiration.
