Abstract:- the antimicrobial potential of seven extracts from four plants was screened against eight bacteria and two pathogenic fungi, using a micro broth dilution assay. The lowest concentration of the extract, which inhibits any visual microbial growth after treatment with p-iodonitrotetrazolium violet, was considered to be a minimum inhibitory concentration (MLC). Water extracts of Acacia nilouca, Justicia zelanica, Lantana camera, and Saraca asoca exhibited good activity against all the bacteria tested and the MIC was recorded in a range of  9.375 – 37.5 μg/ml and 75.0-300.0 μg/ml against the bacterial and fungal pathogens, respectively.

i) Suggest a suitable title to the research work.

ii) Which are the four plant extracts used for study? Which test cultures were used for the research work?

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

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

Q. 4) D) What is plagiarism? Give an example? How would you avoid plagiarism? (7M)


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

a) Totipotency and Cell theory.

b) Auxins in plant tissue culture media.

c) Serum

d)  Trypsinization

e) Non-verbal communication.
