Exercise 3: Link the Word with the Description
Vacuole
Controls what enters and
leaves the cell
Chloroplast
Controls the cell
Cytoplasm
Cell wall
Contains cell sap
Supports plant cells and
is made of cellulose
Cell membrane
Absorbs sunlight for
photosynthesis
Nucleus
Where chemical
reactions occur
1. Which part of the cell controls the cell?
The nucleus.
2. What happens in the cytoplasm?
Where chemical reactions occur.
3. What does the cell membrane do?
Controls what enters and leaves the cell, gives the cell shape.
4. Which three parts are in plant and animal cells?
Nucleus, cytoplasm and cell membrane.
5. Which three parts are only found in plant cells?
Vacuole, cell wall and chloroplasts.
Are all cells the same shape ?
Why do cells have
different shapes?
Specialised Cells 1
A sperm cell
A leaf palisade cell
The sperm cell is adapted to
its function by being
streamlined and having a tail
so it can swim.
The leaf palisade cell has a
large surface area for
efficient gas exchange. It also
has lots of chloroplasts to
absorb sunlight for
photosynthesis.
Specialised Cells 2
A red blood cell
The red blood cell is adapted to
its function by having a large
surface area for efficient
absorption of oxygen.
The ciliated cell has tiny
hairs that filter out dust
from the air you breathe
and move mucus along as
well.
Ciliated cell

Do cells work on their own?
No
What is the name given to a group of similar
shaped cells that do they same job ?
Tissues
A ciliated epithelial cell
What is their function?
Ciliated epithelial
tissue in a lung

Palisade cells are packed
with chloroplasts to help

Work to do
• 1. Use page 10 a& 11 to complete the
worksheet, ‘Special cells’, by writing the
answers on the sheet. Then stick the
worksheet in your book.
• 2. Complete the worksheet 7Ad/4 Tissue
matching and stick it in your book.
All systems go
Muscle
cells are
grouped to
form
muscle
tissue
The heart contains
muscle and nerve
tissues
Nerve cells are grouped to
form nerve tissue
Root hair cells are
grouped together to
form root hair tissue
The root contains
root hair and xylem
tissue
How do we get new cells?
The nucleus splits into two
The new daughter cells get
bigger.
A new cell membrane
forms in the middle
Once the daughter cells
are full size, they can too
can divide
When
things go
wrong.
•1. Put the title New cells
2. Answer questions 3 & 4 from page 13
7Ac/5 Odd cell out
Look at each set of cells. Work out what each
cell is and what it does (its function). Then
decide which is the odd one out.
For example are they plant or animal cells? Do
they have different structures in the cells??
To finish
7Ac Shaped for the job
