Question 1
1 / -0

According to the biological species concept, which of the following statements is not correct?

A
To be considered a species, a population must be reproductively isolated from other species.

B
For a new species to arise, it must be geographically isolated from its parent species for long periods of time.

C
Organisms that are phenotypically identical yet have distinct mating behavior are considered distinct species since they do not naturally interbreed.

D
Organisms that can interbreed and produce sterile offspring are considered distinct species.

Solution

1. For a population to be considered species, they should be closely related organisms that are very similar to each other and are capable of interbreeding and producing fertile offspring. Geographical isolation from other species is not required.
2. Geographic isolation is a common way for the process of speciation to begin. Rivers change course, mountains rise, continents drift, organisms migrate, and what was once a continuous population is divided into two or more smaller populations.
3. Phenotypical similarities are not required for two populations to be considered same species, interbreeding between them is necessary.
4. According to Ernst Mayer biological definition of species, organisms that can interbreed and produce sterile offspring are considered distinct species.
So, the correct option is 'To be considered a species, a population must be reproductively isolated from other species'.
Question 2
1 / -0

Point out the correct method of showing scientific name of coconut palm derived by binomial nomenclature.

A
Cocos nucifera

B
Cocos Nucifera

C
cocos Nucifera

D
cocos nucifera

Solution

The scientific name is used to identify the organisms and to avoid the confusion created by the local names. The scientific name is comprised of the genus and the species. The genus is the first name and the first letter is written in capitals and remaining all are small including the species name. The scientific name of the coconut palm is Cocos nucifera.
Thus, the correct answer is option A.
Question 3
1 / -0

Which taxonomic term may be suggested for any rank in the classification?

A
Class

B
Order

C
Species

D
Taxon
Solution
Taxonomy is the branch of science which deals with the naming and classification of several living organisms on the basis of similarities and dissimilarities.
Taxon is a term used for any rank in the classification.
So, the correct answer is option D.
Question 4
1 / -0

Read the statements given below and identify the incorrect statement.

A
Scientific names are used all over the world

B
Scientific names are often descriptive and tell us some important character of an organism

C
Scientific names indicate relationship between species

D
Scientific names favour multiple naming for the same kind of an organism
Solution
- The organisms are given the scientific name by the scientists. The scientific name is the taxonomic name given to the organism.
- The name is composed of the genus and the species. The names are depending on the genus and species and thus, they describe the organism and the characters and relation of the organism with other organisms in the genus and the species.
- These are the names that are universally accepted and used all over the world.
- The local names favor multiple names and create confusion in identifying the organism.
Thus, the correct answer is option D.
Question 5
1 / -0

The permanent record of plant specimen is called as

A
Botanical garden

B
National parks

C
Museum

D
Herbaria

Solution

A herbarium is a collection of preserved plant specimens. It gives the permanent record of plant specimen. These specimens may be whole plants or plant parts. These are in a dried form mounted on a sheet. The specimens are stored with a data label. Herbariums are essential for the study of plant taxonomy, the study of geographic distributions and the stabilizing of nomenclature. Herbaria may also be a repository of viable seeds for rare species.
Thus, the correct answer is option D.
Question 6
1 / -0

The types of herbaria is based on

A
Purpose

B
Region

C
Plant groups

D
All of the above
Solution
- A Herbarium is defined as a collection of plants that usually have been dried, pressed, preserved on sheets and arranged according to any accepted system of classification for future reference and study.
- The labels on the herbarium sheets provide information regarding place of collection, English, local and botanical names, family, etc.
- The types of herbaria are based on Purpose, region and plant groups.
- So, the correct answer is 'All the above'.
Question 7
1 / -0

Hortorium is associated with

A
Herbarium of wood

B
Herbarium of fungal origin

C
Herbarium of horticulture origin

D
None of the above

Solution

A hortorium is an institution or museum for the collection,preservation and study of horticultural specimens.
Horticulture is a study or practice of growing flowers,fruits and vegetables.
while herbarium is the collection of preserved specimens and their associated data.
So a Hortorium is a herbarium of horticultural origin.
Question 8
1 / -0

In taxonomic hierarchy, the number of common character will increase as we go from

A
Species to Kingdom

B
Kingdom to Species

C
Class to Order

D
Genus to Species

Solution

The hierarchical order of taxonomic categories is a sequence of categories in a decreasing or increasing order from kingdom to species and vice versa. The kingdom has the highest rank followed by division, class, order, family, genus, and species. Species has the lowest rank in the hierarchy.
Thus, the correct answer is 'Species to Kingdom'.
Question 9
1 / -0

Which of the following taxonomic method is used to explain about the fossils

A
Cytotaxonomy

B
Paleobiology

C
Phenetic taxonomy

D
None of the above

Solution

Paleobiology is a branch of Paleontology that deals with the biology of fossils of organisms, both plants and animals. It takes information from geology, paleontology and biology.
So, the correct answer is, 'Paleobiology'.
Question 10
1 / -0

Binomial of vilvam is

A
Acalypha indica

B
Aegle marmelos

C
Cissus quadrangularis

D
Mimosa pudica

Solution

The binomial nomenclature is the system which names the organisms with the help of two words which includes the genus and the species. The binomial name of Vilvam is Aegle marmelos. This is commonly known as the golden apple or stone apple. This fruit is known to have medicinal properties.
Thus, the correct answer is option B.
