SUBJECT: BASIC SCIENCE
TOPIC: Living Things
Sub-topic: Characteristics and Classification of Living Things
LIVING THINGS
Biology is the study of living things. Living things are things which have life in them.
In general, living things are said to have seven characteristics or features. It is not enough to
have some of these characteristics. Living things must have all of the following seven
characteristics:
1. Nutrition
2. Respiration.
3. Excretion.
4. Growth.
5. Reproduction.
6. Movement.
7. Response.
To help to remember these characteristics, use the first letter of each word in the phrase:
Nature Rarely Enjoys Giving Rubbish Much Respect.
Classifying Living Things
Living things are classified into groups in order to simplify their study. Sorting or arranging
living things into groups is referred to as classification.
The two basic groups into which living things are arranged are:
1. the animal kingdom
2. the plants kingdom.
Differences Between Plants and Animals
Plants
Animals
Make their own food
Do not make their own food but feed on
plants or other animals.
Are usually green in colour
Have a variety of colours
Do not have definite shape
Have definite shape
Do not move from place to place, they may
move parts of their bodies.
Move from place to place
Classification of Plants
Plants may be classified into two major groups, these are:
1. Flowering plants: They are plants with well developed roots, stems and leaves. They
produce flowers, fruits and seeds. Examples are Mango, Coconut Oil palm, e.t.c.
2. Non-flowering plants: They are plants which do not produce flowers. Examples are
Mushroom and Spirogyra.
Classification of Animals
Animals can be classified into two;
1. Vertebrate animals: These are animals with backbones and are further grouped into;
(a) Fishes (Pisces) e.g. Tilapia, Shark and Dogfish
(b) Amphibians e.g. Toad and Frogs
(c) Reptiles e.g. Snakes, Crocodiles, Turtle, Lizard Tortoise e.t.c.
(d) Birds (Aves) e.g. Flamingo, Eagle, Pigeon e.t.c
(e) Mammalia (Mammals) e.g. Rabbit, Man, Dog, e.t.c.
2. Invertebrates: These are animals without backbones, there are two types:
(a) Unicellular or single celled animals. Examples are Amoeba and Paramecium
(b) Multi-cellular or many celled e.g. Insects, Crayfish, Scorpion, e.t.c.

ASSIGNMENT :
1. All these are living things except
(a) Monkey (b) Man (c) Car (d) Pawpaw
2. Which of the following characteristics of living things will a newly born baby not be able
to carry out?
(a) Movement (b) Respiration (c) Nutrition (d) Reproduction
3. Animals are different from plants in that they (i.e. animals) cannot
(a) excrete (b) produce their own food (c) move (d) respond to stimuli
4. Which of these is a vertebrate animal.
(a) Snake (b) Housefly (c) Millipede (d) Beetle
4. Give three reasons that allows a human being to be classified as an animal
5. A rabbit is eating grass. Its ears turn to face the direction of a sound and the rabbit stops
eating. As the sound gets louder the rabbit hops away. Name three signs of life shown by the
rabbit.
