The process by which anything is grouped into convenient categories based on some easily observable characters is called

classification

Perfectly

The process of classifying all living organism into different taxa is called

taxonomy

External and internal structure, along with the structure of cell, development process and ecological information of organisms are essential and form the basis of

Modern taxonomic studies

The branch of study of knowing more about different kinds of organism and their diversities, but also the relationships among them was refered to as

systematics

The word systematics is derived from the Latin word-

Systema

Taxon

Each ____ is the unit of classification

category / rank/ taxon

Taxonomic studies consider a group of individual organism with fundamental similarities as a \_\_\_

species

One should be able to distinguish one species from the other closely related species based on the

distinct morphological differences

Consider the following two statements : I : In the single celled organisms, we are not very clear about the usage of the two terms - growth and reproduction. II : When it comes to unicellular organisms like bacteria, unicellular algae or amoeba, reproduction is synonymous with growth 1. Both I and II are two and II explains I 2. Both I and II are two and II does not explains I

Consider the following two statements : I. Cellular organisation of the body is the defining feature of life forms. 2. Metabolic reactions cannot be demonstrated outside the body in cell-free systems 1. Both I and II are two and II explains I 2. Both I and II are two and II does not explains I 3. I is true but II is false 4. Both I and II are false

The most obvious & complicated feature of all living organisms is : 1. The ability to sense heir environment and responds to these environmental stimuli 2. Reproduction - asexual or sexual
