Leaf Cell

cross section through a leaf cell (http://www.bbc.co.uk/schools/gcsebitesize/science/images/aqaaddsci_07.gif)

Leaf Cell:-

 Function:- is to absorb light for photosynthesis

Adaptation:- Closely packed chloroplasts (which have chlorophyll in it) and continuously overlayered for efficient absorption of sun light.

Root Hair cell

Function:-  absorb minerals and water ions from the soil

Adaptation:- Large surface area, due to having long "finger'like" shape.

Sperm Cell

sperm cell - has a head and tail (http://www.bbc.co.uk/schools/gcsebitesize/science/images/aqaaddsci_09.gif)

Function:- To carry the Chromosomes from the male to the female reproductory system (egg) :)

Adaptation:- It has :

  • A head full of DNA information, also has an enzyme to penetrate the egg cell membrane.
  • The middle is filled with mitochondria, full of energy
  • Tail to help move the sperm to egg

red blood cells (http://www.bbc.co.uk/schools/gcsebitesize/science/images/aqaaddsci_10.gif)

Functions:- To carry oxygen around your body (has haemoglobin in it)

Adaptation:- Outer membrane diffuse easily, No nucleus so more space for haemoglobin, Shape increases the surface area to allow oxygen to be absorbed more.
