An attribute found in plants but not animals is

(1) Metabolism

(2) Sexual reproduction

(3) Autotrophy

(4) Asexual reproduction

Which of the following is less general in characters as compared to genus

(1) Species

(2) Family

(3) Class

(4) Division

Consider the following two statements:

I. In the single-celled organisms, we are not very clear about the usage of the two terms – growth and reproduction.

II. When it comes to unicellular organisms like bacteria, unicellular algae or amoeba, reproduction is synonymous with growth, i.e., increase in number of cells.

1. Both I and II are true and II explains I

2. Both I and II are true but II does not explain I

3. I is true but II is false

4. Both I and II are false

Consider the following two statements:

I. Cellular organization of the body is the defining feature of life forms.

II. Metabolic reactions cannot be demonstrated outside the body in cell-free systems.

(1) Both I and II are true and II explains I

(2) Both I and II are true but II does not explain I

(3) I is true but II is false

(4) Both I and II are false

The most obvious & complicated feature of all living organisms is:

(1) The ability to sense their surroundings or environment and respond to these environmental stimuli.

(2) Reproduction - sexual or asexual - for production of progeny of own kind.

(3) The ability to growth in size due to cell division.

(4) Presence of complex organs systems such as digestive and nervous system.

Identify the incorrect statement:

(1) Biological names are generally in Latin and written in italics. They are Latinised or derived from Latin irrespective of their origin.

(2) The first word in a biological name represents the genus while the second component denotes the specific epithet.

(3) Both the words in a biological name, when handwritten, are separately underlined, or printed in italics to indicate their vernacular origin.

(4) The first word denoting the genus starts with a capital letter while the specific epithet starts with a small letter.

The scientific term for biological classification categories is the:

(1) Species

(2) Taxon

(3) Phylum

(4) Domain

What is meant by the "species problem"?

(1) The exact definition of species is still controversial.

(2) The exact mechanisms of speciation is not known.

(3) The number of species present is much more than identified species.

(4) The extinction of species is taking place at an alarming rate.

Which of the following taxonomic categories are correctly matched to their standard termination of names with respect to biological classification of plants?

(1) I, II, IV

(2) I, II, III

(3) II, III, IV

(4) I, II, III, IV

Consider the following statements:

I. Higher the taxa, more are the characteristics that members whithin the taxon share.

II. Lower the category, greater is the difficulty of determining the relationship to other taxa at the same level.

Of the two statements:

(1) I is true but II is false

(2) I is false but II is true

(3) Both I and II are true

(4) Both I and II are false
