TASK Name three living things and three
non living things
Cells differ in shape and size.
They carry out different
tasks. Cells have three main
parts:- The membrane is the
covering around the
cell.
- The nucleus is the part
which controls the cell.
- The cytoplasm is
between the nucleus
and the membrane. Plants cells also have a hard
cell Wall around the
membrane.CELLS
TASK Draw the animal cell
and the plant cell.

Living things are classified into groups called kingdoms. The principal kingdoms are the
animal kingdom, the plant kingdom and the other kingdoms such as the fungi kingdom.
Others are bacteria, virus and protist.
Animals are multicelular living things that eat
other living things. They can move from one place
to another, and they can react quickly to stimuli.
To do this, they have a nervous system and sense
organs.
Plants are multicellular living things that use
sunlight and substances from the soil and air to
make their own food. Plants cannot move around
because they are fixed to the ground.
Fungi can be unicellular, but most are
multicellular. Like animals, fungi do not
make their own food. They depend on
other organisms for food.

Bacteria are the most abundant of all living things.
Bacteria are the smallest living things. Bacteria are
unicelullar and can live in different environments: in
wáter, soil, air or inside other living things.
Viruses are so small and simple that scientists cannot
agree if they are living things or not. For this reason,
they are not included in any of the five kingdoms.
Viruses can only reproduce inside other living things.
They cause illnesses.
TASK Classify these organisms.
