Learning outcomes• Be able to name some specialised
cells• Describe the jobs of some
specialised cells• Describe how specialised cells are
adapted for their jobs

Specialised Cells• Plants and animals are multicellular (consist of
many cells).• They contain many different types of cells.• Each type of cell is designed to carry out a
particular job or function.• This is known as CELL SPECIALISM• Not all cells look the same.• Some cells have a special shape and features to
help them do a certain job.

Sperm cell
The head contains enzymes which allow it to digest into an egg cell and join with it.
Head nucleus
Tail
Designed to Fertilise eggs.
A sperm is small and has a long tail that provides movement so it can swim and find an egg cell.
Found in the Testes

Egg (Ovum) Cell
• Designed to be Fertilised.
• Found in the Ovaries.
• An egg cell is large and bulky.
• Contains yolk which provides a large food store for the new cell being formed.
Cytoplasm containing yolk
Layer of jelly

Palisade Cell
• Designed for Photosynthesis
• Found in the top of a leaf
• Tall and has a large surface area to absorb water and minerals.
• Packed with chloroplasts to help make plant food.

Root Hair Cell• Designed for
absorbing.
•Thin cell wall makes it easy for minerals to pass through.
•Has a large surface which helps it to absorb water and minerals.
•Found in a plant root.

Nerve Cell (neurone)
•They are long •They have connections at each end •Can carry electrical signals •Their job is to carry nerve impulses to different parts of the body.

Red Blood Cell
•Designed to carry oxygen •Found in blood.•Large surface area, for oxygen to pass through. •Contains haemoglobin, which joins with oxygen.•Has no nucleus

Model Cell
1. Decide which cell you know the least about.
2. Make a model cell using coloured paper.
3. Make sure you add as many labels as possible.

Peer assessment
1. Look at the model cell of the person next to you. – Have they included the job of the cell?– Have they included the adaptations of the cell?
2. Write them a www and an ebi
