Tendrils in plants are an example of
- convergent evolution
- radiation
- divergent evolution
- co-evolution
The Correct Option is C
Approach Solution - 1
Approach Solution -2
Evolution: Evolution is the generational change in the heritable traits of biological populations.
These traits are manifestations of genes that are handed down through reproduction from parent to child.
Genetic recombination and mutation result in different traits.
When evolutionary forces like natural selection and genetic drift work on this variety, specific traits within a population start to become more or less prevalent, and this is when evolution happens.
Evolution brings biodiversity.
Convergent evolution: Convergent evolution is the process by which similar features develop in several species.
For instance, despite having no biological connection, sharks and dolphins have many physical characteristics.
Adaptive radiation is a process in which organisms quickly evolve from a progenitor species.
The term "homologous organs" refers to organs with the same developmental origin, a similar structure, and a dissimilar function. For instance, the tendril of the Cucurbita and the thorn of the Bougainvillaea. Both thorns and tendrils are axillary in location and evolved from axillary buds.
Both of them serve different purposes; for example, thorns provide protection, while tendrils provide support.
Therefore, plant tendrils are an illustration of diverse evolution.
Coevolution is a sort of evolution in which two or more species interact with one another and occasionally develop a relationship of mutual benefit.

Concepts Used:
Stem - Nodes and Internodes
Underground Modification
In some plants, stems are modified to form underground structures that store food. Some examples of the underground stem are as follows:
Rhizome: They are non-green, fleshy structures that resemble roots in appearance. The presence of nodes and internodes distinguishes them from roots. When a rhizome grows horizontally, it is called Straggling Rhizome. This type of rhizome is seen in turmeric, ginger, etc. If a rhizome grows in an oblique direction, it is called RootStock Rhizome. This is found in bananas and alocasia.
Therefore it has nodes and internodes. Ginger is a stem and not a root because it has nodes and internodes. It is a rhizome, an underground modification of the stem.
