The Living World (past 10 years) Flashcards
- Select the correctly written scientific name of Mango which was first described by Carolus Linnaeus. (2019)
a. Mangifera indica Car. Linn.
b. Mangifera indica Linn.
c. Mangifera indica
d. Mangifera Indica
b. Mangifera indica Linn.
Name of the author appears after the specific epithet, i.e., at the end of the biological name and is written in an abbreviated form, e.g., Mangifera indica Linn. It indicates that this species was first described by Linnaeus.
Other universal rules of nomenclature are as follows:
1. Biological names are generally in Latin and written in italics.
They are Latinised or derived from Latin irrespective of their
origin.
- The first word in a biological name represents the genus while
the second component denotes the specific epithet. - Both the words in a biological name, when handwritten, are
separately underlined, or printed in italics to indicate their Latin
origin. - The first word denoting the genus starts with a capital letter
while the specific epithet starts with a small letter. It can be
illustrated with the example of Mangifera indica.
- Study the four statements (A–D) given below and select the two correct ones out of them: (2016-II)
A. Definition of biological species was given by Ernst Mayr.
B. Photoperiod does not affect reproduction in plants.
C. Binomial nomenclature system was given by R.H.Whittaker.
D. In unicellular organisms, reproduction is synonymous with growth.
The two correct statements are
a. A and D
b. A and B
c. B and C
d. C and D
a. A and D
A. Definition of biological species was given by Ernst Mayr.
D. In unicellular organisms, reproduction is synonymous with growth.
A. Ernst Mayr (1904 – 2004) He also pioneered the currently accepted definition of a biological species
B. Photoperiod affects reproduction in seasonal breeders, both plants and animals
C. Biologists follow universally accepted principles to provide scientific names to known organisms. Each name has two components – the Generic name and the specific epithet. This system of providing a name with two components is called Binomial nomenclature. This naming system given by Carolus Linnaeus is being practised by biologists all over the world.
D. When it comes to unicellular organisms like bacteria, unicellular algae or Amoeba, reproduction is synonymous with growth, i.e., increase in number of cells.
