Question

Axenic culture is
(A) Pure culture without any contamination
(B) Pure culture without any nutrient
(C) Culture of a tissue
(D) Culture of gene

Answer 1

Hint: Axenic is defined as the nation of the way of life in which the particular species or the variety or the strain of the particular organism is solely present in the subculture except the existence of any different microorganism. This type of way of life is feasible for each unicellular microorganism and also multicellular organisms.

Complete answer:
This axenic culture is broadly speaking observed for microorganisms like bacteria and other unicellular eukaryotic organisms.

In this culture, the organisms are used and it is diluted to give rise to many subsamples. The dilution of the way of life is made in such a way that the subsamples efficaciously contains solely one organism in case of the asexual organisms or two organisms in case of sexual organisms.

These subsamples are cultured to produce the pure axenic culture. The culture medium is checked periodically in order to find whether or not the way of life is contaminated or in the axenic condition.

After that the subculture is checked for its contamination. The sample is kept on the agar plate. Since the agar is the enriching medium for the boom of microorganisms, the contaminating organisms grow via getting the nutrients from it. If the lifestyle is pure, no organisms grow from the agar plate.

Hence, the correct answer is option (A)

Note: This lifestyle is primarily used for the cause of the study of the traits of the parasitic and the symbiotic organisms in the managed tradition condition. For example, this is used in the lifestyle of entamoeba, fungi increase in the lichens etc.
