NCERT solutions for class 11 biology chapter 1 the living world - Solved Exercise Questions:

Q1. Why are living organisms classified?

Answer:

Living organisms are classified because of the following reasons

1. Due to a large variety of life forms on earth, it becomes difficult to study each of the species, thus scientists classify these species into larger groups, wherein by studying a group, we can deduce the characteristics of all the species. Hence living organisms are classified for the ease of studying them.

2. Classifying organisms into groups and sub-groups may also aid in establishing evolutionary relationships between them.

Q2. Why are the classification systems changing every now and then?

Answer:

Earth is a home for numerous species of plants, animals and microbes. The exact count of these life forms is still unknown. Scientists have discovered many species present on Earth. These have been properly named and classified as per the existing classification systems. However, there are still so many species to be discovered. Whenever new species are discovered the classification systems are modified according to the requirements. Therefore, the classification systems are always dynamic and they keep on changing as per the needs.

Q4. What do we learn from identification of individuals and populations?

Answer:

The identification of individuals based on their characteristics helps us to know how an individual differs from the other members of the population and in what points it is similar to the population. It also helps us in deriving relationships between individuals of different population. Such relationships help in classifying organisms in their right groups. Learning the characteristics of populations aid in the study of that population as well as how it can be related to the other populations. Through this practice, e can establish evolutionary relationships between different populations.

Q7. Can you identify the correct sequence of taxonomical categories:

(A) Species $\rightarrow$ Order $\rightarrow$ Phylum $\rightarrow$ Kingdom

(B) Genus $\rightarrow$ Species $\rightarrow$ Order $\rightarrow$ Kingdom

Answer:

The correct sequence of taxonomic categories from lowest to highest is species, genus, family, order, class, phylum, kingdom. Thus, A and C represents the correct sequence of taxonomic categories with some categories missing in between while B is incorrect as the genus is given before species.
