CLASSIFYING LIVING THINGS
Living things are classified into five large
groups called kingdoms. All the living things in the same kingdom have similar
characteristic.
3.1 THE FUNGI KINGDOM
Fungi cannot move around or make their own
food. They eat the remains of other
living things. There are two types of fungy:
- Unicellullar fungi. Yeasts are in
this group because they have one cell.
- Multicellullar fungi. Moulds and
mushrooms are in this group. They have lots of cells that group together in filaments
called hyphae.
3.2 THE PLANT KINGDOM
Plants are multicellular organisms that cannot
move around. They make their own food from the nutrients they get from the
soil, air, water and sunlight. There are two types of plants:
- Plants with flowers. They use seeds
to reproduce.
- Plants without flowers. They do not
use seeds to reproduce.
3.3 THE ANIMAL KINGDOM
Animals are multicellular organisms. Most can
move around. They eat other living things because they cannot make their own
food. There are two main groups:
- Vertebrates. They have a spine.
People are vertebrate animals.
- Invertebrates.
They don´t have a spine.
3.4 TWO SIMPLE KINGDOMS
The simplest living things belong to two
kingdoms. Most are very small and almost all of them are unicellular, bacteria.
- Bacteria. The cells of the living
things in this kingdom do not have a membrane separating their nuclei from
their cytoplasms.
- Other simple organisms. Living
things in this kingdom, like amoeba and algae, have simple structures.
