Binomial system of nomenclature means that every organism has___________

  1. Two names, one scientific and the other popular

  2. One name given by two scientists

  3. One scientific name consisting of a generic and specific name

  4. A number in an international catalogue by which it can be identified
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
 C Linnaeus, the father of taxonomy, introduced the binomial system of nomenclature. He dealt about this in the 10th edition of his book 'Systema Naturae' which was published in 1785.
This is a system of providing organisms with distinct scientific names which consist of two words, the first one indicating a generic name (Genus). The first and second together form a specific name (Species). These two words are in Latin or Latinized if derived from other languages.
Genus is a common noun and starts with a capital letter. It indicates the name of a group. In the specific name, the second word is like an adjective and begins with a small letter excepting the cases when it denotes proper nouns like the name of a person, place or the like. It may then, start with a capital letter.
The names when written should be underlined to indicate their Latin origin. In the printed form, they should be italicized.
The name of the author who has first described the plant in scientific journals may be appended in full or abbreviated form. For example - the botanical name of mango is Mangifera indica Linn. All three comprise binomial nomenclature.
The generic name is one for all species whereas the species name is variable. For example - Ficus bengalensis, Ficus religiosa, Ficus glomerata, which represent banyan, peepul and fig trees respectively. All have one generic name Ficus but their species names are F.bengalensis, F.religiosa, F.glomerata.

A major problem with polynomial names was that they were

  1. Inaccurate

  2. Cumbersome

  3. Not descriptive

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

  • The term nomenclature means the scientific naming of organisms according to an established system. In earlier days common vernacular names were used which generally changes with change of language. Later in the haunt of one common internationally accepted name for a species, scientific names (Technical names) have been introduced in the form of polynomial, binomial and trinomial systems of nomenclature.
  • In the early seventeenth century, taxonomists started using a string of descriptive Latin words to designate a species. For example, in the herbal of Clusius (1583) a species of willow is named as Salix pumila angustifolia altera.
  • Polynomial nomenclature was discarded for the two main reasons that it was lengthy and difficult to remember, it often varies from place to place, scholar to scholar based on the characters chosen by them.
So the correct option is 'Cumbersome'.

  Organisms such as  plants that use light to make their own food are known as 

  1. Heterotrophs

  2. Photoautotrophs

  3. Symbionts

  4. Parasites

  5. Herbivores
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
A. Heterotrophs are the organisms that feed on autotrophs or producers for their food.
B. Photoautotrophs are the organisms that use the light energy and convert it into chemical energy to make their food. For example, plants.
C. Symbionts are the organisms that form association with other organisms. The association may be commensalism, mutualism, parasitic etc.
D. Parasites are the organisms that live within or on an other organism which is called the host.
E. Herbivores are the primary consumers that feed directly on the producers (plants).
Hence organisms such as plants that use light to make their own food are known as photoautotrophs.
So, the correct answer is 'Photoautotrophs'.
