Which of the following represents a type of interaction where one species helps the other in nutrient absorption while receiving energy-yielding carbohydrates in return?
Mycorrhizae, a form of mutualism, involves fungi helping plants absorb nutrients and plants providing carbohydrates to the fungi, fitting the description exactly.
Which of the following statements about nomenclature is correct?
The text states: 'Obviously, nomenclature or naming is only possible when the organism is described correctly and we know to what organism the name is attached to. This is identification.' Therefore, nomenclature presupposes correct description and identification.
The scientific names for plants are based on principles and criteria provided in which international code?
The text explicitly mentions: 'For plants, scientific names are based on agreed principles and criteria, which are provided in International Code for Botanical Nomenclature (ICBN).'
Who is credited with giving the system of Binomial Nomenclature?
The text states: 'This naming system given by Carolus Linnaeus is being practised by biologists all over the world.'
In the scientific name Mangifera indica, what does 'indica' represent?
The text explains: 'In this name Mangifera represents the genus while indica, is a particular species, or a specific epithet.'
According to the universal rules of nomenclature, what is the correct way to write a biological name when handwritten?
The rules state: 'The first word in a biological name represents the genus while the second component denotes the specific epithet.' and 'Both the words in a biological name, when handwritten, are separately underlined, or printed in italics to indicate their Latin origin.' While the capitalization rule isn't explicitly stated in the context for handwriting (but implied by example 'Mangifera indica'), the underlining rule is clear for both words separately.
Why are biological names generally in Latin and written in italics?
The text states: 'Biological names are generally in Latin and written in italics. They are Latinised or derived from Latin irrespective of their origin.'
Which of the following is NOT a universal rule of nomenclature as described in the provided text?
The text lists three rules: Latin origin, genus as the first word and specific epithet as the second, and separate underlining for handwritten names. It does not mention that the specific epithet must always be a descriptive adjective.
The purpose of scientific names, as established through codes like ICBN and ICZN, is to ensure:
The text states: 'The scientific names ensure that each organism has only one name. Description of any organism should enable the people (in any part of the world) to arrive at the same name.'
What is the primary reason for the need to standardize the naming of living organisms?
The text explains: 'These local names would vary from place to place, even within a country. Probably you would recognise the confusion that would be created if we did not find ways and means to talk to each other, to refer to organisms we are talking about. Hence, there is a need to standardise the naming of living organisms...'
