Red blood cellsRed blood cells

Structure:• Large surface area• Contains haemoglobin which picks

up oxygen• Has no nucleus to make room for

more oxygen

Function:• Carries oxygen from the lungs to

the body and carbon dioxide from the body back to the lungs.

Red Blood CellsRed Blood Cells

Red blood cellsRed blood cells

Function:• These cells are found in your blood.• They are attracted to diseases and bacteria that enter your body• They then ‘eats’ any bacteria/disease so the microbe can’t infect

you and make you ill

White Blood CellsWhite Blood Cells

Nerve cellsNerve cells

Structure:• These are extremely elongated (long) cells• They have many branches at both ends to

connect to other nerve cells• The long axis (main branch) is covered in fat to

prevent the electrical impulses affecting the surrounding parts of your body

Function:• To carry nerve impulses around your

body

Sperm cellsSperm cellsSperm CellSperm Cell

Structure:• Have a long tail so they can swim to find an egg• There are enzymes (like scissors) in the head of the

sperm to help the sperm get into the egg• Made in the testis of males

Function:• To carry the father’s genetic information (DNA) to the egg

Sperm cellsSperm cellsMuscle CellMuscle Cell

Structure:• Arranged in bundles called muscle fibres

Function:• Can contract which makes the fibres shorter and

causes bones to move or helps substances move around the body.

Sperm cellsSperm cellsBone CellBone Cell

Function:• Collect calcium from food and allow the growth

and repair of bones• They build up bone around themselves, creating

the body’s skeleton.

Sperm cellsSperm cellsFat CellFat Cell

Structure:• Have a large vacuole in which to store fat molecules

Function:• Protection of vital organs• Insulation• Long-term energy storage

Root hair cellsRoot hair cellsRoot Hair CellRoot Hair Cell

Structure:• Large surface area to absorb lots of

water• Thin cell wall to allow water to pass

through easily• Doesn’t contain any chloroplasts unlike

all other plant cells

Function:• Absorbs minerals and water from soil

Palisade Cell

Structure:• Found in the top of a leaf• Tall and has a large

surface area to catch as much sunlight as possible

• Packed with chloroplasts to absorb sunlight

Function:• to carry out

photosynthesis• to help make plant food.

Palisade CellPalisade Cell

Structure:• They line all the air passages

down to the lungs.• They have tiny hairs called cilia.

Function:• Designed to stop Lung Damage• Hairs sweep mucus with trapped

dust and bacteria back up the throat to be swallowed.

• If you smoke then the hairs die and the mucus builds up leading to the well known smoker’s cough

Egg (Ovum) CellStructure:• Contains yolk that acts as a food source for the developing embryo (baby)

when fertilised• Much larger than other animal cells (look at the size of the sperm next to it!)

Function:• Carries the mother’s DNA
