Animal Cells and Plant cells
Lesson Objectives
1) To be able to correctly label the main parts of animal and
plant cells
2) To be able to describe their functions
3) Know some examples of cells
Animal and plant cells
Here is a picture of a plant
cell and an animal cell.
Cells are the smallest
units of life.
Some cells can exist on
their own, whilst others
are found in groups.
Humans are a collection of
many billions of cells, all
working together.
What is a cell?
Label these Cells on your sheet.
Nucleus
Cell Membrane
Cytoplasm
Cell Wall
Vacuole
Chloroplast
Plant Cell
Animal Cell
The Cell - a living factory!
Role Check
Do all cells look the same?
We now know that most cells have three basic parts. These
are the:
Nucleus
However, cells can be
different shapes and
sizes and also have
different functions. This
is because they are…
Cytoplasm
Cell Membrane
Specialised
This means that
their shape is
related to their
function.
Let us look at some animal cells
These are common animal cells. Scraped
from a person’s cheek.

Notice the rigid
shape from the
cell wall.
Plant Cells
The black
dots are the
nuclei
Plant Cells have something else too. Do
you know what’s missing?
Chloroplasts!
These are
the green bits
Of course all of these cells add up to
make a beautiful…
Plant or flower!
Plants have specialised cells too…
Think about what plants need to survive:
Water
Sunlight
CO2
Plants draw up the water from the soil…
The root looks like this close up
Plants also need Carbon Dioxide.
These pictures you can see are special holes, called
stomata. They are found on the underside of some
leaves.
Sunlight is turned into food
Sunlight is
absorbed by the
chloroplasts in the
leaves.
Chloroplasts
contain chlorophyll,
which is green.
Sunlight is absorbed by the chloroplasts
Remember those
green bits?
