An attribute found in plants but not animals is

(1) Metabolism

(2) Sexual reproduction

(3) Autotrophy

(4) Asexual reproduction

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

Study the four statements (I-IV) given below and select the two correct ones out of them:

I. Definition of biological species was given by Ernst Mayr.

II. Photoperiod does not affect reproduction in plants.

III. Binomial nomenclature system was given by RH Whittaker.

IV. In unicellular organisms, reproduction is synonymous with growth.

The two correct statements are

(1) II and III

(2) III and IV

(3) I and IV

(4) I and II
