The Correct Option is A

Solution and Explanation

Rauwolfia vomitoria is a medicinal plant used in modern medicines because of the presence of certain alkaloids in its plant parts. This plant reveals genetic variation in different Himalayan ranges in terms of the potency and concentration of an active chemical. The amount and variety of these chemicals change both between the Rauwolfia species and between the different strains of R. vomitoria. Because of the increasing demand and decreasing natural resources, there is an attempt to develop new strains suitable for agricultural production.

Notes on Biodiversity and Conservation

Concepts Used:

Biodiversity and Conservation

The term ‘biodiversity’ is derived from the two words- ‘bios' which means life and ‘diversity’ i.e, differentiation or variation. Edward Wilson, the sociobiologist was the first to popularise the term ‘biodiversity’ in the year 1992. The term implies the occurrence of various plants and animals along with their variants such as biotypes, ecotypes and genes on earth. In our biosphere, the immense diversity or heterogeneity remains not only at the species level but also, at every level of biological organization that ranges from macromolecules in the cells to biomes.

Biodiversity and Conservation is a topic covered under the fifteenth chapter and Unit 5 of NCERT class 12 biology.
