What makes species a basic taxonomic category?
Species is the lowest of a population or basic taxonomic category which consists of one or more individuals that resemble one another more closely than individuals of other species. The members of a species interbreed freely and are reproductively isolated from members of other species. These featurRead more

See lesscategory which consists of one or more individuals that
resemble one another more closely than individuals of

The members of a species interbreed freely and are
reproductively isolated from members of other species.
These features make the species basic taxonomic
category.
Why there is a need to standardise the system of naming of living organisms?
There are millions of living organisms in the world. Often, these organisms are known by their local names that vary from place to place, even within a country. Hence, the naming process of living organism is standardised in a way that a particular organism is known by the same name all over the worRead more
There are millions of living organisms in the world.
See lessOften, these organisms are known by their local names
that vary from place to place, even within a country.
Hence, the naming process of living organism is
standardised in a way that a particular organism is
known by the same name all over the world in the
scientific community.
All the organisms are not yet identified on the earth. Justify the statement.
There are diverse habitats on earth hosting millions of living organisms. Due to limited number of taxonomists, absence of thorough survey of different areas and occurrence of several inaccessible regions, e.g., hot springs, underwater reefs, etc., it is difficult to identify all the organisms.

A plant may have different names in different regions of the country or world. How do botanists solve this problem?
Botanists use binomial nomenclature to solve this problem. A scientific name is given to the plant based on certain principles and criteria. The scientific name ofa particular plant is same all over the world and is not given to any other plant.

How are plants kept in museums?
In museums, specimens are preserved in containers or jars in preservative solutions. Plant and animal specimens may also be preserved as dry specimens.

Write examples of two species, each belonging to same genera.
Panthera leo (lion), P. pardus (leopard). Solanum tuberosum (potato), S. melanogena (brinjal).

Brinjal and potato belong to the same genus Solanum, but two different species. What defines them as separate species?
Brinjal and potato both belong to same genus as they share some common correlated characters. They belong to different species because they have (i) different morphological features. (ii) reproductive isolation (inability to interbreed).

What do we learn from identification of individual and populations?
Identification of individuals and populations categorise it into a specific species. Each species has unique characteristic features. On the basis of these features, it can be distinguished from other closely related species,

How are living organisms divided into different taxa? What is the name given to this process?
Living organisms can be divided into different taxa based on their characteristics. This process of classification is called taxonomy.
