4
This is a plant.
These are plants.
5
Whats this?
Its a virus.
These are viruses.
6
This is a bacterium.
These are bacteria.
7

These are fungi.
8
There are five kingdoms of organisms.
Viruses
Bacteria
Fungi
Plants
Animals
9
Whats this?
Its a cell.
You need a microscope to see some cells.
10
How many cells are there in the picture?
There are 33 cells.
11
Which is which?
an animal cell a plant cell a bacterial cell
12
Plant cells can use photosynthesis, because ...
... theyve got chloroplasts.
13
What can you see in the cell?
cell membrane
cell wall
vacuole
nucleus
nuclear membrane
mitochondrion
cytoplasm
chloroplast
14
This is a plant cell structure with organelles.
cell membrane
cell wall
vacuole
nucleus
nuclear membrane
mitochondrion
cytoplasm

15
Which organisms have got cell walls around their
cells?
Bacteria
Fungi
Plants
Animal cells havent got cell walls.
Viruses arent cellular organisms.
16

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.
18
Read the text and check your worksheet.
C) Bacteria are unicellular organisms.
Bacterial cells are very small. They havent
got a nuclear membrane, but they have got a cell
wall.
19
Read the text and check your worksheet.
D) Viruses are smaller than bacteria. They arent
cellular organisms.   E) Fungi can be
unicellular or multicellular organisms. Fungal
cells have got a cell wall, but they havent got
chloroplasts. Fungi cant use photosynthesis to
get food.
20
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 havent got a
cell wall and they havent got chloroplasts.
21
There are five kingdoms of organisms.
Viruses
Bacteria
Fungi
Plants
Animals
