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
same species.
Plants can´t move
Plants can make their food
Apple tree Roses Moss Plant
Flowering plants
Apple trees have got flowers
Apple trees can´t move
Apple trees can make
their own food
Moss hasn´t got flowers
Moss can´t move.
Moss can make its own food
Non–flowering plants
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
from long. Thin Filaments called
hyphae. They produce spores.
Some mushrooms are edible
but others are poisonous.
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
Yeast are microsc beopic fungi. They
Don´t have hyphae and they don´t produce
Mushrooms. We use yeasts to make foods such
as wine, bread and cheese.
(levadura)
Microorganisms
Microorganisms are very small living things.
Some microorganisms can make yoghurt.
Some microorganisms produce illnesses.
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.
They depend on living things
to survive.
Viruses cause some
illnesses such as flu.
We use vaccines to protect
us from viruses.
