What is Cladophyll in plants?
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.
Is Cladophyll and phylloclade same?
The two terms are used either differently or interchangeably by different authors. [Examples provided]: Ruscus, Phyllanthus and some Asparagus species. In some plants, the petioles are flattened and widened, to become phyllodes or phyllodia, or cladophylls and the true leaves may be reduced or absent.
Is Opuntia a phylloclade?
Thus in absence of leaves to perform photosynthesis, Stem becomes broad, flat green and fused with chlorophyll that acts as a leaf. Thus the modification of stem to leaf like strucutre is called phylloclade. Opuntia has phylloclade.

What is Bulbil in plants?

What is the function of Rhizome?
rhizome, also called creeping rootstalk, horizontal underground plant stem capable of producing the shoot and root systems of a new plant. Rhizomes are used to store starches and proteins and enable plants to perennate (survive an annual unfavourable season) underground.
What is runner stem?
In botany a stolon—also called a runner—is a slender stem that grows horizontally along the ground, giving rise to roots and aerial (vertical) branches at specialized points called nodes. In zoology, stolons of certain invertebrate animals are horizontal extensions that produce new individuals by budding.
Is Opuntia a phyllode?
So, the correct answer is B – phylloclade.
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.
