They are multiple organisms
that work together but don't do
the same things.
Specialised animal
cells
Muscle cells: There are 3
types of muscles that are
the voluntary mucles, the
involuntary mucles and the
cardic muscles
The involuntary muscles ( also known
as skeltal muscles) are the
musclesattached to the bone of your
skelton. They are used for support nd
movement. The reason the are called
voluntary musle is because you are
able to control what they are and
aren,t able to do
Involuntary muscle work
without you having to
think about it. An example
is when you breathe in
and out
Cardical muscle are the muscles
that make up the heart. The are
involuntary muscles put have
striped apperances like a
voluntary muscle
Blood cells: There are two
types of blood cells: red
and white.
White blood cells are part of the
immune system and help fight
infections
The red blood cells carry
oxygen around to your cells
where it is used to realise the
energy you need. It also
carries some of the waste
carbon dioxide from the cells
too get rid of it.
Nerve cells:They make up your
brain and also carry information
from your brain to other parts
of your body
Fat cells: There
are 2 types of
fat cells
Brown fat cells are used to produce heat for the body
White fat cells store energy.
They also form an insulating
layer under the skin to keep
your body at a constant
temperature
Animals are complex multicellar
organisms with large numbers of
different cell types
Specialised plant
cells
Plants have multicellular organisms. They
have specialized cells with different shape
and sizes but don't have as many
different types of cells like animals. Some
of the multicellular organisms consist of:
Guard cells : They are found
on leaves and stems of
plants. They are cells that
work together to open and
close stomata
Conducting cells: They are
long, thin tubes like drinking
straws. They transfer water
from the roots to the leaves
Photosynthetic cells: They are near the
surface of the green part of the stem
and have a large nuber of chloroplasts
Structural cells: The cell wall acts
as the skeleton of the plant. When
the plant becomes bigger, the cell
wall grows along with it.
Root hair: They are extensions
on the outer surface of some
root cells which allows a
larger surface area for water
uptake
