Q. 4) C) Read the following abstract and answer the following questions. (8M)

Abstract: – Essential oils are complex volatile compounds, synthesized naturally in different plant parts during the process of secondary metabolism Essential oils have a great potential to destroy several bacterial, fungal, and viral pathogens. The presence of different types of aldehydes, phenolics, terpenes, and other antimicrobial compounds means that the essential oils are effective against a diverse range of pathogens. The reactivity of essential oil depends upon the nature, composition, and Orientation of its functional groups. The aim of this research article was to test the antimicrobial potential of essential oils secreted from 10 plants and their possible mechanisms of action against human pathogens. The 6 plant extracts showed antimicrobial action against both gram-positive and gram-negative bacteria. The extracts of mentha and clove showed maximum inhibition zone thus showing potent antimicrobial activity. The method used for the study was Agar cup assay

i) Suggest a suitable title to the research work

ii) What are essential oils and which are the active compounds present?

iii)  What is the method used fat study? what was the result of the study?

vi) Give four keywords for the research work based on the abstract


Q. 4) D) Compare and contrast Verbal and Non Verbal communication. (7M)


Q. 5) Write Short notes on any three of the following. (15M)

a) Cell theory

b) Role of cytokines in plant tissue culture media.

c) Applications of animal cell culture.

d) Inverted microscope

e) Principles of effective communication.
