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?

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.

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

Ciliated cell

The ciliated cell has tiny hairs that filter out

dust from the air you breathe and move

mucus along as well.

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.

Page 14: Cells Animal cells Plant cells Specialised cells Organisation Organ systems.

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

Page 15: Cells Animal cells Plant cells Specialised cells Organisation Organ systems.

Root hair cells are grouped together to form root hair tissue

The root contains root hair and xylem tissue

Page 16: Cells Animal cells Plant cells Specialised cells Organisation Organ systems.

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

•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??
