• Which part of the cell controls the cell?
• What happens in the cytoplasm?
• What does the cell membrane do?
• Which three parts are in plant and animal cells?
• Which three parts are only found in plant cells?

The nucleus.
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.
6
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
The leaf palisade cell has a large surface area
for efficient gas exchange. It also has lots of
chloroplasts to absorb sunlight for
photosynthesis.

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.

shaped cells that do they same job ?
Tissues
A ciliated epithelial cell What is their function?
Ciliated epithelial tissue in a lung

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.

14
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
15
Root hair cells are grouped together to form root
hair tissue
The root contains root hair and xylem tissue
16
How do we get new cells?
The nucleus splits into two
A new cell membrane forms in the middle
The new daughter cells get bigger.
Once the daughter cells are full size, they can
too can divide
17
When things go wrong.
18

• 1. Put the title New cells
• 2. Answer questions 3 4 from page 13

19
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??
