What’s this? It’s a bat.
The bat is an animal.
What are these? They are animals.
This is a plant.
These are plants.
What’s this?
It’s a virus.
These are viruses.
This is a bacterium.
These are bacteria.
This is a fungus.
These are fungi.
There are five kingdoms of organisms.
Viruses
Plants
Bacteria
Animals
Fungi
What’s this?
It’s a cell.
You need a microscope to see
some cells.
How many cells are there in the picture?
There are 33 cells.
Which is which?
an animal cell
a plant cell
a bacterial cell
Plant cells can use photosynthesis, because ...
... they’ve got chloroplasts.
What can you see in the cell?
cell membrane
cell wall
vacuole
nucleus
nuclear membrane
mitochondrion
chloroplast
cytoplasm
This is a plant cell structure with organelles.
cell membrane
cell wall
vacuole
nucleus

Which organisms have got cell walls
around their cells?
Plants
Fungi
Bacteria
Animal cells haven’t got cell walls.
Viruses aren’t cellular organisms.
These are unicellular organisms.
These are multicellular organisms.
Read the text and check your worksheet.
A) Cells are the basic units of life. Every cell
has got a cell membrane, organelles and
cytoplasm.
B) Plants, animals and fungi have got a
nucleus inside their cells.
Around the nucleus there is a nuclear
membrane.
Read the text and check your worksheet.
C) Bacteria are unicellular organisms.
Bacterial cells are very small.
They haven’t got a nuclear membrane, but
they have got a cell wall.
Read the text and check your worksheet.
D) Viruses are smaller than bacteria. They
aren’t cellular organisms.
E) Fungi can be unicellular or multicellular
organisms.
Fungal cells have got a cell wall, but they
haven’t got chloroplasts. Fungi can’t use
photosynthesis to get food.
Read the text and check your worksheet.
F) Plant cells have got a cell wall,
chloroplasts or vacuoles.
These cells can use photosynthesis to get
food.
G) Animal cells haven’t got a cell wall and
they haven’t got chloroplasts.
There are five kingdoms of organisms.
Viruses
Plants
Bacteria
Animals
