Which type of microorganism is specifically responsible for ripening Roquefort cheese, imparting its characteristic flavor?
The provided text states, 'The ‘Roquefort cheese’ are ripened by growing a specific fungi on them, which gives them a particular flavour.'
Microbes are extensively used in industrial production. Which of the following is NOT an example of their industrial application mentioned in the context?
The text states, 'Even in industry, microbes are used to synthesise a number of products valuable to human beings. Beverages and antibiotics are some examples.' While construction materials are listed as general economic benefits from nature in another chapter, they are not specifically linked to microbial industrial production in the provided context.
Which of the following vessels are typically used for growing microbes on an industrial scale for product synthesis?
The NCERT text explicitly mentions, 'Production on an industrial scale, requires growing microbes in very large vessels called fermentors (Figure 8.4).'
Microbes are integral components of biological systems and can be found in various extreme habitats. Which of the following is NOT described as an extreme habitat where microbes exist?
The text states, 'They are present even at sites where no other life-form could possibly exist– sites such as deep inside the geysers (thermal vents) where the temperature may be as high as 100°C, deep in the soil, under the layers of snow several metres thick, and in highly acidic environments.' The sun's core is not mentioned.
In the context of the diversity of microbes, which of the following is NOT listed as a type of microbe?
The text mentions, 'Microbes are diverse– protozoa, bacteria, fungi and microscopic animal and plant viruses, viroids and also prions that are proteinacious infectious agents.' Archaebacteria are a type of bacteria but not listed separately as a distinct category in this particular enumeration of microbial diversity.
What is the primary reason for the characteristic texture, flavor, and taste of different varieties of cheese?
The text states, 'Different varieties of cheese are known by their characteristic texture, flavour and taste, the specificity coming from the microbes used.'
Which of the following is a common method for cultivating microbes in a laboratory for study, allowing them to form visible colonies?
The text explains, 'Microbes like bacteria and many fungi can be grown on nutritive media to form colonies (Figure 8.3), that can be seen with the naked eyes. Such cultures are useful in studies on micro-organisms.'
Which Kingdom, according to Whittaker's Five Kingdom Classification, primarily consists of autotrophic and heterotrophic bacteria and is known for its extensive metabolic diversity?
The summary states, 'In the five kingdom classification, bacteria are included in Kingdom Monera...These organisms show the most extensive metabolic diversity. Bacteria may be autotrophic or heterotrophic in their mode of nutrition.'
Which component of the cell wall in bacteria, belonging to Kingdom Monera, distinguishes it from the cellulosic cell wall of green plants?
Table 2.1 under the 'Monera' row states that the cell wall is 'Noncellulosic (Polysaccharide + amino acid)'.
