SpeciesTwo living things belong to the same species

when they can reproduce and have a fertile

offspring.

Dogs all belong to one species.However, horses

and donkeys don´t belong to the same species.

Their offspring are mules that cannot reproduce.

Horse + donkey = Mules are not fertile.

There is only one species of human

beings.

We may have different hair or skin

colour but we all belong to the

FungiFungi can´t move.

Fungi can´t make their own food.

Mushrooms are fungi.

Mushrooms can´t move.

Mushrooms can´t make

their own food. They get

food from the remain of other

living things.

Mushrooms are part of fungi

that grow under the ground.

They are the visible part that

We can see. Mushrooms grow

Moulds are fungi.

Moulds can´t move.

Moulds can´t make

their own food.

Moulds appear on

certain food like bread.

Moulds are made up

of many hyphae.

Moulds feed on

decomposing

material.

We can make

antibiotics, such as

penicillin, from

moulds

Yeast

BACTERIA

They are the smallest

micro-organisms. We

can only see them with

microscopes.

There are beneficial

bacteria, such as those

that turn milk into

Yoghurt.

Other bacteria causes

illnesses.

We treat illnesses

causes by bacteria with

antibiotics.

VIRUSES

Viruses aren´t living things

because

They don´t carry out life

processes.
