Exercise 1: Label the Animal Cell
Exercise 2: Label the Plant Cell
Exercise 3: Link the Word with the Description
Controls the cell
Contains cell sap
Controls what enters and leaves the cell
Supports plant cells and is made of cellulose
Absorbs sunlight for photosynthesis
Where chemical reactions occur
1. Which part of the cell controls the cell?
2. What happens in the cytoplasm?
3. What does the cell membrane do?
4. Which three parts are in plant and animal cells?
5. Which three parts are only found in plant cells?
Where chemical reactions occur.
Controls what enters and leaves the cell, gives the cell shape.
Nucleus, cytoplasm and cell membrane.
Vacuole, cell wall and chloroplasts.
Why do cells have different shapes?
Are all cells the same shape ?
Specialised Cells 1
The sperm cell is adapted to its function by being
streamlined and having a tail so it can swim.
A sperm cell
A leaf palisade cell
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
The red blood cell is adapted to its function by
having a large surface area for efficient absorption of
oxygen.A red blood cell
The ciliated cell has tiny hairs that filter out
dust from the air you breathe and move
mucus along as well.
Exercise 5: Link the Cells with the Diagram
Red blood cell
Do cells work on their own?What is the name given to a group of similar shaped cells that do they same job ?
A ciliated epithelial cell
What is their function?
Ciliated epithelial tissue in a lung
Cells to Tissues
Nerve cell Nerve tissue
Special cells found in plants
A root hair cell takes in water Root hair
Palisade cells are packed with chloroplasts to help the plant make food Palisade
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 new daughter cells get bigger.
The nucleus splits into twoA 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??
7Ac Shaped for the job
Match the columns
Exercise 6: Match the Words and Diagrams
Exercise 10: Name the Systems
