What is the common term used for members of Phylum Porifera?
The first line under Phylum Porifera states, 'Members of this phylum are commonly known as sponges.'
Which of the following taxonomic categories, when arranged in an ascending hierarchical order, comes immediately after 'Family' but before 'Class'?
The taxonomic hierarchy in ascending order is Species, Genus, Family, Order, Class, Phylum/Division, Kingdom. Therefore, 'Order' comes immediately after 'Family' and before 'Class'.
As we move from species to kingdom in the taxonomic hierarchy, what happens to the number of common characteristics shared between members within a taxon?
As stated in the NCERT text: 'as we go higher from species to kingdom, the number of common characteristics goes on decreasing. Lower the taxa, more are the characteristics that the members within the taxon share.'
In the classification of plants, what is the higher category assigned to classes with a few similar characters?
The NCERT text states: 'In case of plants, classes with a few similar characters are assigned to a higher category called Division.'
According to the provided table, which taxonomic category does 'Homo' represent for 'Man'?
Looking at Table 1.1, for 'Man', the 'Biological Name' is 'Homo sapiens', and 'Homo' is listed under the 'Genus' column.
'Taxon' is defined as:
The NCERT text mentions: 'Each category, referred to as a unit of classification, in fact, represents a rank and is commonly termed as taxon (pl.: taxa).' It also says, 'These taxonomic groups/categories are distinct biological entities and not merely morphological aggregates.' Furthermore, based on characteristics, organisms are grouped into categories, and these categories are taxa. So all options are relevant to the definition of a taxon.
Which of the following organisms belongs to the Class Dicotyledonae?
Referring to Table 1.1, Mango (Mangifera indica) belongs to the Class Dicotyledonae, while Wheat (Triticum aestivum) belongs to Monocotyledonae, and Housefly and Man are animals.
The problem of classification becomes more complex as we move to higher categories because:
The NCERT text states: 'Higher the category, greater is the difficulty of determining the relationship to other taxa at the same level. Hence, the problem of classification becomes more complex.' While common characteristics decrease, the complexity arises from establishing relationships at the same level.
What is the primary requirement for placing an organism in various taxonomic categories?
The text states: 'Now the question you may ask is, how to place an organism in various categories? The basic requirement is the knowledge of characters of an individual or group of organisms. This helps in identifying similarities and dissimilarities among the individuals of the same kind of organisms as well as of other kinds of organisms.'
For organisms like Housefly, Man, Mango, and Wheat, the highest common taxonomic category mentioned in Table 1.1 is:
Looking at Table 1.1, 'Phylum/Division' is the highest common category explicitly listed for all four organisms before the Kingdom, which acts as the ultimate division into broad groups like Animalia and Plantae.
