(a)(i) Characteristic of Living organisms:
- Movement/locomotion
- Excretion
- Respiration
- Reproduction
- Irritability/sensitivity/response
- Growth/development
- Nutrition/feeding
- Competition
- Adaptation
- Life span/death
(ii) Movement: 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.
Excretion: This involves the removal/getting rid of waste products of cell metabolism; membole wastes are poisonous if allowed to accumulate.
Respiration This is the breakdown/burning of food substances; by aerobic/anaerobic respiration; to release energy needed for all processes of life.
Reproduction: 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.
Irritability: Response/ reaction of organisms; towards changes in the environment; to ensure survival. Nutrition: the process involved in obtaining/manufacturing food; can be autotrophic/heterotrophic; and utilizing it for growth and maintenance/life processes.
Growth: This is the irreversible increase; in size and weight of an organism; which leads to complexity and maturation.
Competition: Ability of organisms to struggle; for all necessity of life; to survive in their environment.
Adaptation: Ability of organisms to adjust; to changes in environment; for survival.
Life span/death: All living organisms have definite period of existence; all organisms die.
b Differences between plants and animals;

Animals	plants
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/leaf
Heterotrophic mode of nutrition that depend on already-made food	Autotrophic mode of nutrition/ manufacture their own food using the energy from the sun
No chlorophyll/chloroplast	chlorophyll/chloroplast present
No cell wall	Has a cell wall made of cellulose
sense organs present	sense organs absent
Growth is limited/definite, growth in all parts of the body	growth is unlimited/indefinite .growth is apical or terminal
stores carbohydrates as glycogen	stores carbohydrates as starch
Has special excretory body	No special excretory body
Response is fast, short termed	response very slow/short termed
Respiratory organs present	No respiratory organs

(c)(i) Name of organism:
Euglena/Chlamydomonas.(ii) Animal features: For Euglena
— Gullet for feeding.
— Has flagellum for locomotion in water.
— Myonemes for movement.
— Has pellicle that gives it a definite shape.
— Has eye spot to detect light intensity.
— Has contractile vacuole for osmoregulation and excretion.
Plant features:
- Definite shape.
— Has chioroplasts containing chlorophyll used to absorb light.
— Paramylum granules.
— Pyrenoid.
