Task 3: Specialised Cells

Year 7 Independent Learning Project. (ILP)
Ensuring Excellence
Subject: Science
ILP Title: Cells
In this project you will learn:
The basic structure of a plant and animal cell
The function of the different parts of these cells
How cells may become specialized to carry out certain
functions within living organisms
Time you should spend on
this project:
3 hours
At the end of this project you should hand to your teacher:
Task 1: Using a microscope (11 marks)
Task 2: Cell Structure (20 marks)
Task 3: Specialised Cells (29 marks)
You should break down your time in the following way:
30 minutes on Task 1
1 hour on Task 2
1.5 hours on Task 3
Weblinks you should use to help you with this task:
 www.lgfl.skoool.co.uk/keystage3.aspx?id=63
 Then follow links; Click on London Grid; KS3 Biology
Use a search engine such as www.google.co.uk; search for www.skoool.co.uk or
www.bbc.co.uk/bitesize/ks3/science and ‘search’ on these websites for cell structure.
Your parents may be able to help you by:
Looking at your work in the booklet and checking you have completed all the tasks.
Helping you to use the internet to find scientific definitions of key words.
Helping you to use these key words to answer the questions in the booklet.
If you need extra help the SEN department has additional sheets that may be completed and
attached to your booklet.
Your work will be assessed by:
A total mark /60 will be awarded.
The key words to learn in this project are:
Cell membrane
Cell wall
Cell Specialisation
Blood Cell
Root hair cell
Nerve Cell
Palisade Cell
All living things are made from cells. We cannot see cells with the
naked eye as they are MICROSCOPIC. We need a microscope to see

 Complete the labels on the two diagrams below
 Use the ‘Using a microscope’ option (Number 10) to help you
You would put your specimen onto one of these to place onto the
stage of the microscope…
You may see these down the microscope…

Q3. Microscopes can MAGNIFY the image you can see.
Does magnify mean to make an object bigger or smaller?
(1 mark)
Q4. A microscope that allows you to see MORE DETAIL is said to
give more RESOLUTION.
Which of the following two pictures, A or B, provides the greater
degree of resolution?
(1 mark)
Cells contain structures that have different jobs to help the cell
carry out its function.
 Log onto:www.bbc.co.uk/bitesize/ks3/science/organisms_behaviour_health/c
 Read through page 2 on Cells.
 You will see pictures here of what real plant and animal cells
look like down a microscope.
 Read through page 3.
 You will see here diagrams of how plant and animal cells are
drawn in science books.
Q5. Draw and label a diagram of each cell below:-
(10 marks)
Task 2 continued
 Research the answers to the following questions
 Find these answers in the wordsearch on the next page:-
Q6. What structure controls which substances enter and leave
Q7. Where do most chemical reactions occur?
Q8. Where is most of the genetic information found?
Q9. What structures, only found in plant cells, allow a plant to make
glucose by photosynthesis?
Q10. What is found in the nucleus that may also be worn on ‘out of
school uniform days’?
Q11. What green pigment allows a plant to absorb light energy?
Q12. What substance is found inside the vacuole?
Q13. What substance in plant cells walls, is tough and offers plant
cells more support?
Q14. What is found outside a plant cell membrane to offer support
to plants?
Q15. What structure inside plant cells offers extra support and
keeps them firm?
(10 marks)
A specialised cell is a cell with SPECIAL FEATURES to help it carry
out a particular function in a living organism.
