Mark the incorrect one (with respect to taxonomic key)

1. Based on contrasting characters

2. Generally analytical in nature

3. Each statement is called couplet 

4. used for identification of plants or animals

 

Animals, dogs and mammals represent

1. Taxa at different levels

2. Taxonomic hierarchy

3. Taxa at equivalent level

4. Categories at equivalent level

Living organisms exhibit distinctive characteristics to differentiate from non-living objects. Which one of the following statements can be considered as defining property of living things?

1 Increase in body mass as a criterion for growth

2 Reproduction is synonymous with growth in unicellular organisms

3 Ability of living organisms to sense their surroundings

4 Metabolic sections that can be demonstrated outside the body in cell-free system only

First step of taxonomy is

1 Classification

2 Nomenclature

3 Identification

4 Characterisation

Biologists have established certain procedures and techniques to store and preserve the information as well as specimens. Amongst these which one has collection of both preserved plant and animal specimens?

 1 Zoological parks

2 Herbarium

3 Museum

4 Botanical gardens

Mark the correct statements with respect to living organisms 

1 Growth and cellular organisation are considered as defining properties of living organisms

2 Reproduction can be all inclusive defining characteristic of living organisms

3 Living organisms are self replicating, self regulating and evolving interesting systems

4 isolated metabolic reactions in vitro are living things

Study of diversity of organisms and evolutionary relationship amongst them on the basis of all possible characters is called as

1 Taxonomy

2 Systematics

3 Alpha-taxonomy

4 Phylogeny

Which statements is incorrect with respect to genus?

1 Each genus may have one or more than one specific epithets

2 It comprises a group of related species

3 It has more characters in common in comparison to species of other genera

4 Potato and brinjal belong to different genus

Choose the wrong statements with respect to distinguishing characteristics of living beings

1 In majority of higher, the growth and reproduction are mutually exclusive events

2 Degrowth will occur when catabolism exceeds anabolism

3 Isolated metabolic relations in-vitro are neither living things nor living reactions

4 Growth cannot be taken as a defining property of living organisms if we take increase in body mass as a criterion on growth

Select incorrect statements with respect to living beings

1 Growth cannot be taken as a defining property of living organisms

2 Growth can be easily observed in vitro culture

3 Metabolic reactions cannot be demonstrated outside the body in cell-free system

4 All organisms, from the prokaryotes to the most complex eukaryotes can sense and respond to environmental cues
