Most names in biological nomenclature of living organisms are taken from which language?

  1. Hindi

  2. Latin

  3. German

  4. French
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The original scientific names were taken from Latin and Greek languages. New names are now derived either from Latin language or are latinised. This is because Latin language is dead and therefore, it will not change in form or spellings with the passage of time.

A living organism is unexceptionally differentiated from a non-living structure on the basis of

  1. Reproduction

  2. Growth and movement

  3. Interaction with environment

  4. Responsiveness
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
All organisms, from primitive prokaryotes to most advanced and complex eukaryotes, are able to sense and respond to environmental factors. The stimuli are perceived by sense organs in higher animals through sensory receptors in the eyes, ears, nose etc. Plants do not possess such sense organs. However, they do respond to external factors such as light, water, temperature, pollutants, other organisms, etc. Human beings have an additional facility of self consciousness (awareness of self). Consciousness and response to stimuli are said to be defining properties of living organisms.
So the correct option is D.

Read the following statements and select the correct ones.


(i) An increase in mass is a characteristic of living organisms
(ii) Metabolic reactions can be demonstrated outside the body in isolated cell-free systems.
(iii) 'Response to stimuli' is a defining property of living organisms.

  1. (i) and (ii)

  2. (ii) and (iii)

  3. (i) and (iii)

  4. (i), (ii) and (iii)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

(i) Increase in mass and increase in number of individuals are twin characteristics of growth is true
(ii) Metabolic reactions can be demonstrated outside the body in isolated cell-free systems is true
(iii) 'Response to stimuli' is a defining property of living organisms is true

So, the correct option is '(i), (ii) and (iii)'.

There are various types of reproduction. The type of reproduction adopted by an organism depends on

  1. The habitat and morphology of the organism

  2. Morphology of the organism

  3. Morphology and physiology of the organism

  4. The organisms habitat, physiology and genetic makeup
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
There are various types of reproduction, both asexual (fission, budding, etc.) and sexual (internal and external). The type of reproduction, an organism undergoes depends ultimately on its genetic makeup which influences its physiology. Habitat also influence the type of reproduction, that organism undergoes.
So, the correct answer is 'The organisms habitat, physiology and genetic makeup'.

  2. Taxonomy

  3. Hierarchy

  4. Key

C Correct answer
Explanation

Hierarchy of categories is the classification of organisms in a definite sequence of categories(taxonomic categories) in a descending order starting from kingdom and reaching upto species or an ascending order from species of kingdom.

The scientific name of banyan is written as Ficus benghalensis L. Which of the following statements is correct regarding this?

  1. Letter L. signifies Latin language

  2. The name should be written reverse with benghalensis preceding Ficus

  3. Letter L. signifies the taxonomist Linnaeus

  4. Benghalensis is a generic name
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In binomial nomenclature, the first or generic word starts with a capital letter while the second word or specific epithet starts with a small letter. The name of taxonomist appears after the specific epithet, i.e., at the end of the biological name and is written in abbreviated form, e.g., Ficus benghalensis L., indicates that this species was first described by Linnaeus.

___________ is a life process that is not essential for an individual's survival but for survival of the species.

  1. Growth

  2. Reproduction

  3. Respiration

  4. Nutrition
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Reproduction is a biological process in which an organism produces young ones (offspring) of the same species. It is one of the most important characteristic of the living organisms. Reproduction is essential for the survival of species but not for the survival of individuals.
So, the correct answer is 'Reproduction'.

One-celled organisms can respond to stimuli.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Response to stimuli also known as sensitivity is shown by all the living organisms whether it is unicellular or multicellular. This is essential for one-celled organisms for their survival. For example, if a unicellular organism is exposed to a chemical, it will react either by producing another chemical or by moving away from the stimulus to survive. 

Thus, the correct answer is option A.

The term 'taxon' is used for __________________.

  1. The ranks of species and genus

  2. The ranks up to phylum

  3. The species epithet only

  4. Any rank of taxonomic hierarchy
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Taxon is a unit of classification which may represent any level of grouping of organisms based on certain easily observable common characteristics. Mayr $(1964)$ has defined taxon to be a taxonomic group of any rank that is sufficiently distinct to be worthy of being assigned to a definite category.
