We are surrounded by living and nonliving things. All animals and plants are living things and biology is the study of these living things. A cat playing with a ball is obviously living. A pigeon flying from tree to tree is also a living thing. Sometimes it is not as easy to decide. Plants are living things, but they do not play with balls or fly. If something is living it will carry out all of the seven characteristics like movement, breathing or respiration, excretion, growth, sensitivity and reproduction. Some non-living things show one or two of the seven characteristics of living things. Like crystals such as ice crystals forming on a window, grow bigger if the conditions are right. But still they cannot be categorised as living.
(i) Which of the following is a defining characteristic of living organisms?
(a) Growth
(b) Ability to make sound
(c) Reproduction
(d) Response to external stimuli
(ii) The most important feature of all living systems is to
(a) utilise oxygen to generate energy
(b) replicate the genetic information
(c) produce gametes
(d) utilise solar energy for metabolic activities
(iii) In which of the following, metabolic reactions take place?
(a) In living organisms
(b) Both in living and non-living organisms
(c) In isolated cell-free systems
(d) Both (a) and (c)
(iv) Why reproduction cannot be considered as an inclusive defining characteristic of all living organisms?
(a) Non-living organisms also reproduce

(v) Which one of the following aspects is an exclusive characteristic of living things?
