Weekly Quiz Competition

Question 1
1 / -0

All living organisms are linked to one another because.

A
They have common genetic material of the same type

B
They share common genetic material but to varying degrees

C
All have common cellular organisation

D
All of the above

Solution

All organisms share common genetic material, i.e., DNA and RNA. However, it can vary to certain degrees.
Question 2
1 / -0

Which of the following 'Suffixes' used for units of classification in plants indicates a taxonomic category of 'family'?

A
-Ales

B
-Onae

C
-Aceae

D
-Ae
Solution
Correct Option: C
Explanation:
- The ‘family’ in taxonomy consists of common attributes among animals belonging to one or more genera.
- This part of the taxon ends with –Aceae.
- It was introduced by Carolus Linnaeus when he denoted major groups of trees.
- Examples: Datura And Petunia belongs to the same family Solanaceae.
Hence the correct option is –Aceae.
Question 3
1 / -0

The term 'systematics' refers to.

A
Identification and study of organ systems

B
Identification and preservation of plants and animals

C
Diversity of kinds of organisms and their relationship

D
Study of habitats of organisms and their classification

Solution

Systemaics is the branch of study of diversity of organisms and all comparative and evolutionary relationship between them.
Question 4
1 / -0

Tanvi bought ten food items from the supermarket, which are wheat, bananas, mushrooms, onions, Porphyra(Laver), Kelps, pine seeds, Sphagnum moss, lady's fingers and potatoes. Based on hierarchical classification, how many different phyla/divisions do these items belong to?

A
$$3$$

B
$$4$$

C
$$5$$

D
$$6$$

Solution

Item Phylum/Division

Wheat, banana, onion lady's finger, potato

Angiospermae
Pine seeds Gymnospermae
Sphagnum moss Bryophyte
Porphyra (Laver), kelps Thallophyta
Mushrooms Basidiomycota
Question 5
1 / -0

Match the following and choose the correct option.
A. Family i. Tuberosum
B. Kingdom ii. Polymoniales
C. Order iii. Solanum
D. Species iv. Plantae
E. Genus v. Solanaceae

A
i-D, ii-C, iii-E, iv-B, v-A

B
i-E, ii-D, iii-B, iv-A, v-C

C
i-D, ii-E, iii-B, iv-A, v-C

D
i-E, ii-C, iii-B, iv-A, v-D
Solution
- Tuberosum is a species of Solanum tuberosum.
- Polymoniales is an order of the family Solanaceae.
- Solanum is a genus of Solanum tuberosum (potato), Solanum melongena (brinjal), etc.
- Plantae is a kingdom that consists of algae, bryophytes, pteridophytes, gymnosperms, and angiosperms.
- Solanaceae is a family that contains generas such as Datura, Petunia, Solanum, etc.
- So, the correct answer is option A.
Question 6
1 / -0

Which of the following is a defining characteristic of living organisms?

A
Growth

B
Ability to make sound

C
Reproduction

D
Response to external stimuli

Solution

In physiology, a stimulus is a perceptible change in the interior or outside condition. The capacity of a living being or organ to react to those changes is called irritability or responsiveness to stimulus
So, the correct option is 'Response to external stimuli'.
Question 7
1 / -0

Which of the following statements is incorrect?

A
Term 'Nothospecies' refers to the naturally occurring interspecific hybrids

B
As the species do not change with time, therefore they are considered as static groups

C
Metabolism and response to external stimuli are considered as the defining properties of living organisms

D
Hibiscus rosa-sinensis belongs to the same family to which Althaea rosea and Gossypium hirsutum belong to

Solution

Sexual reproduction, a key feature of species, results in the production of offsprings different from the parents due to recombination and mutations. This shows that the species may change with time. Thus, the species are really dynamic groups and not static as held earlier.
Question 8
1 / -0

As we go from species to kingdom in a taxonomic hierarchy, the number of common characteristics.

A
Will decrease

B
Will increase

C
Remain same

D
May increase or decrease

Solution

As we go from species to kingdom in an ordered chain of command, the number of basic qualities (a) will diminish. For Example, the mango tree (Mangifera indica) is under kingdom Plantae and in addition, the unicellular green growth Chlamydomonas is additionally under kingdom Plantae, however, they have just a single likeness that both deliver chlorophyll and have cell divider. every single other trademark is dissimilar.
So, the correct option is 'Will decrease'.
Question 9
1 / -0

The taxonomic unit 'Phylum' in the classification of animals is equivalent to which hierarchical level in classification of plants?

A
Class

B
Order

C
Division

D
Family

Solution

Phylum/Division is a taxonomic category higher than that of class and lower than that of kingdom. The term phylum is used for animals while the term division is used for plants. A division or phylum is formed of one or more classes. The Phylum Chordata or animals contains various classes such as Aves, Reptilia, Amphibia, Cyclostomata, Chondrichthyes, Osteichthyes, Mammalia, etc. The division Angiospermae of plants consists of two classes- Dicotyledonae and Monocotyledonae. So, the correct answer is 'Division'.
Question 10
1 / -0

A group of closely related, structurally and functionally similar organism which interbreed with one another in nature, but not with organisms of other groups is known as

A
Order

B
Genus

C
Species

D
Family
Solution
- Species: a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. The species is the principal natural taxonomic unit, ranking below a genus and denoted by a Latin binomial, e.g. Homo sapiens.
- A genus is a rank in the biological classification (or taxonomy). It stands above species, and below families. A genus can include more than one species. When biologists talk about a genus, they mean one or more species of animals or plants that are closely related to each other.
- A family is one of the eight major taxonomic ranks; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks above the rank of genus.
So, the correct answer is 'Species'.
