(ii) State four animal features and two plant features possessed by theorganism named in 1(c)(i) [6 marks]
Explanation of characteristics of living Organisms
Living things change the position of the whole body/parts of the body;
from one place to another; in search of food/shelter/mates, etc.
This involves the removal/getting rid of waste products of cell metabolism;
metabolic wastes are poisonous if allowed to accumulate.
This is the breakdown/burning of food substances; by aerobic/anaerobic respiration;
to release energy needed for all processes of life.
This is the ability of living organisms to produce new individuals of their own
kind; this ensures the continuity of the species of an organism.
Response/reaction of organisms; towards changes in the environment; to ensure
The process involved in obtaining/manufacturing food; can be autotrophic/
heterotrophic; and utilizing it for growth and maintenance/life processes.
This is the irreversible increase; in size and weight of an organism; which
leads to complexity and maturation.
Ability of organisms to struggle; for all necessity of life; to survive in their
Ability of organisms to adjust; to changes in environment; for survival.
All living organisms have definite period of existence; all organisms die.
(b) Differences between plants and animals
– Move from place to place/locomotion; move with the whole body
Are fixed/do not move from place to place; and move only parts of the body, root/stem/leaves;
Autotrophic mode of nutrition/manufacture their own food using the energy from the sun;
Sense organs absent;
Has a cell wall made of cellulose;
Growth is unlimited/indefinite; growth is apical or terminal;
Store carbohydrate as starch;
No special excretory organs;
Response very slow/long termed;
No respiratory organs;
