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

Abstract: A wide range of medicinal and aromatic plants (MAPs) have been explored for their
essential oils in the past few decades. Essential oils are complex volatile compounds, synthesized naturally in different plant parts during the process of secondary metabolism. The goals of the study were to determine and compare the phytochemical screening, antioxidant and antimicrobial activities of the essential oils of Azadirachta indica and Vitex negundo. The phytochemical screening of the two plants showed presence of alkaloids, carbohydrates, glycosides, phenolic and tannin compounds, flavonoids, saponins, lipids, and terpenoids. About the antioxidant potential, Azadirachta indica showed a higher ability to scavenge free radicals as compared to Vitex negundo, which was investigated by (DPPH) radical scavenging assay. Regarding the antimicrobial activity, Vitex negundo showed a better ability to inhibit the growth of pathogenic micro-organisms as compared to Azadirachta indica, which was investigated by the Agar diffusion method.

i) Suggest a suitable title to the research work.

ii) What is the goal of the study?

iii) Which among the two plants exhibited better antioxidant activity?

iv) Give four keywords for the research work based on the abstract.

Q. 4) D) Explain the important differentiating points of verbal and non-verbal communication. (7M)

Q. 5) Write short notes on (Any three) (15M)

1) Use of rotary shakers in PTC lab.

2) Importance of callus culture.

3) Inverted microscope.

4) Importance of effective communication.

5) Growth factors.
