Specialization in cells.

Cells in multi-cellular organisms are specialised (adapted) so that they can perform a particular function

muscle cells
Muscle Cells
  • Function: to pull on a bone
  • Adaptation: have fibres which can contract (shorten)
ciliated cells6
Ciliated cells
  • Function: to prevent dirt and bacteria from entering the lungs
  • Adaptation: have cilia which move and sweep the dirt and bacteria trapped in the mucus back along the airways
nerve cell8
Nerve cell
  • Function: to transmit messages around the body
  • Adaptation: has a long extension so that messages can be transmitted a long distance
red blood cells
Red blood cells
  • Function: to carry oxygen
  • Adaptation: contains the red pigment haemoglobin which combines with oxygen in the lungs
sperm cell
Sperm cell

Tail-movement of this propels sperm cell

Mid-piece-provides energy

Head-contains the nucleus

sperm cell12
Sperm cell
  • Function: to fertilise an egg cell
  • Adaptation: has a tail which can move and propel sperm cell towards an egg cell
root hair cell
Root hair cell

Root

Hair cell

root hair cell15
Root hair cell
  • Function: to absorb water and dissolved minerals from the soil
  • Adaptation: the long thin projection (‘hair’) provides a large surface area through which the water and dissolved minerals can enter the cell
leaf cells
Leaf cells

chloroplast

leaf cell18
Leaf cell
  • Function: to make food (by process of photosynthesis)
  • Adaptation: has chloroplasts (containing green pigment chlorophyll that absorbs light energy needed for photosynthesis)
