Question 1

As we go from species to kingdom in a taxonomic hierarchy, the number of common characteristics.

Accepted Answer

As we go from species to kingdom in an ordered chain of command, the number of basic qualities (a) will diminish. For Example, the mango tree (Mangifera indica) is under kingdom Plantae and in addition, the unicellular green growth Chlamydomonas is additionally under kingdom Plantae, however, they have just a single likeness that both deliver chlorophyll and have cell divider. every single other trademark is dissimilar. So, the correct option is 'Will decrease'.

Question 2

Define a taxon. Give some examples of taxa at different hierarchical levels?

Accepted Answer

A particular level of hierarchy in the classification of living beings is called as a taxon. A taxon is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit.For example, the basic level of classification is species, followed by genus, family, order, class, phylum or division, in ascending order. The highest level of classification is known as a kingdom. So each of these categories can be called as a taxon.

Question 3

Define and understand the following terms:(i) Phylum (ii) Class (iii) Family (iv) Order (v) Genus

Accepted Answer

Explanation:(i) Phylum- Phylum is a level of taxonomic rank that exists below the kingdom and above the class. e.g. phylum chordata. Equivalent of phylum is division in plant kingdom.(ii) Class- A class is a taxonomic rank that exists below the phylum and above the order. e.g. class mammalia, class aves.(iii) Family-  Family is a taxonomic rank in biological classification that exists below order and above genus. e.g. family hominidae(iv) Order- Order is a taxonomic rank that exists below class and above family. e.g. order primates.(v) Genus- Genus is a taxonomic rank in the biological classification that exists below family and above species. e.g. homo

Question 4

The correct sequence of taxonomic categories is _________________.

Accepted Answer

There are seven main taxonomic ranks: kingdom, phylum or division, class, order, family, genus, species. The hierarchy is Division  \rightarrow  Class  \rightarrow  Order  \rightarrow  Family  \rightarrow  Genus  \rightarrow Species.So, the correct answer is option D.

Question 5

What is the correct sequence of taxonomic categories?

Accepted Answer

Correct Option:
B

Explanation:

Species contain a group of individuals that have common
fundamental similarities. Genus contains a group of related species. Tribe is a rank that lies between
genus and family.Family has a group of related
genera.Order has a group of related families.Class comprises of related orders.Division is a
rank equivalent to phylum.

Hence, the correct sequence of taxonomic categories is division,
class, order, family, tribe, genus, species.

Question 6

Which of the following is correct hierarchical order of taxonomic categories?

Accepted Answer

The hierarchical order of taxonomic categories is a sequence of categories in a decreasing or increasing order from kingdom to species and vice versa. The kingdom has the highest rank followed by division, class, order, family, genus, and species. Species has the lowest rank in the hierarchy. Kingdom: The topmost taxonomic category. Example: All animals are included in Kingdom Animalia. The unit in classification that denotes the grouping of organisms based on features which are observable is known as a taxon.Phylum: It is a term used for animals while its synonym division is used for plants. It is a collection of similar classes. Phylum Chordata of animals has class Mammalia along with birds, reptiles, and amphibians.Class: One or more than one order makes a class. Class Mammalia includes all mammals which are bats, rodents, kangaroos, whales, great apes, and man.Order: One or more than one similar families constitute an order. Family: It is defined as a collection of similar genera. It can be separated from genera by reproductive and vegetative features. For example, cats and leopard are included in the same family.Genus: It is defined as a group of similar species.Species: Group of a population which is similar in form, shape and reproductive features so that fertile sibling can be produced. Thus, the correct answer is 'Kingdom, phylum, class, order, family, genus, species.'

Question 7

The common characteristics between tomato and potato will be maximum at the level of their ____.

Accepted Answer

As we move from higher to lower rank of taxonomical hierarchy, common characters increase. Genus is the lowest common level of tomato and potato as both of them belong to genus 'Solanum'. It means they show all the common characters used to describe genus 'Solanum'.Thus, the correct answer is 'Genus.'

Question 8

Which of the following is less general in characters as compared to genus?

Accepted Answer

The correct hierarchy of classification of various taxons in descending order is given by :Kingdom → Phylum → Class → Order → Family → Genus → SpeciesThe kingdom is the highest taxon with the least similar characters shared between its various members while species is the lowest level with almost similar morphological and behavioral similarities. Species is followed by Genus with slightly fewer similarities among its members.So, the correct answer is 'Species'

Question 9

Which one of the following sequences shows the correct hierarchy of classification, going from the most inclusive to the least inclusive?

Accepted Answer

Most inclusive means the taxons which includes most variety of organisms or plants despite of differences.Thus, it should start from the higher taxon- that is Domain and end with the least inclusive - that is species (with maximum similarity).The sequential order is:Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species

Question 10

Which of the following taxonomic group contains the greatest number of organisms?

Accepted Answer

The number of organisms increases from Species to Kingdom, whereas number of similar characteristics decreases from species to kingdomAmong class, order, phylum, family, the taxonomic category which is placed below the kingdom and is with higher number of organisms is phylum.So, the correct option is 'Phylum'.
