The document discusses the similarities and differences between animal, plant, and bacterial cells, emphasizing cell specialization and various cell types for specific functions. It outlines examples of specialized cells like sperm, egg, palisade, ciliated, root hair, nerve, and red blood cells, detailing their unique features and roles. Additionally, it includes questions to enhance understanding of the material presented.

•Summary questions

3. 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.

4. Questions
• Use the information from these
slides to complete a table as shown
on the worksheet
Specialised cells activity 1

5. Sperm cell
• The head contains
enzymes which allow it to
digest into an egg cell
and join with it.
Head contains enzymes & 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

6. 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
Nucleus

7. 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.
Nucleus
Chloroplasts

8. Ciliated Cell
• Designed to stop Lung
Damage
• They line all the air
passages in the lungs.
• They have tiny hairs called
cilia.
• Hairs sweep mucus with
trapped dust and bacteria
back up the throat.
Nucleus
cilia

9. 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.
Vacuole
Cell membrane
thin cell wall

10. 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.
Nucleus

11. 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

12. Questions
