DO YOU REMEMBER? Vertebrates and invertebratesAnimals are divided into two big groups: vertebrates and invertebrates. Vertebrate animals are divided have
got a skeleton and a spinal column Invertebrate animals haven´t got a
skeleton or a spinal column

ANIMALS Animals share these characteristics They feed on other living things Most animals can move about Most of them can be seen the naked eye

PLANTS Plants share these characteristics: They make their own food They cannot move about Most of them can be seen with the
naked eye.

ALGAE Algae share these characteristics: They make their own food They live in water Some algae can be seen with the naked
eye, and can even be several metres long. Other algae are very small, and you need a microscope to observe them.
Algae are similar to plants, but there are some differences

FUNGI Fungi share these characteristics: They feed on other living thing They cannot move about Some fungi can be seen with the naked
eye, for example mushrooms. Other fungi are so small that you need a microscope to observe them

TYPES OF FUNGI There are different types of fungi. These
are the main types:
Mushrooms: These are the visible part of a fungus. The hidden part is made up of a web of tiny filaments that spread underground to absorb food

TYPES OF FUNGI
Yeast: These are very small. You can only see the with a microscope
Moulds: These a grow on some types of decaying food, such as fruit.

BACTERIA Bacteria can be found everywhere. They
are the smallest and simplest living things. You need a microscope to observe them.
Some bacteria make their own food. Others feed on other living things
Some bacteria live inside other living things. Some of these bacteria help the organism to function, well and others can cause illnesses

BACTERIA Some bacteria are very useful. For
example, we use a bacteria to make yoghurt, vinegar and medicines.
