Specialised Cells
- Palisade Leaf Cell
- The Palisade cell is labelled
'C'
- Near the top layer so they're near to the light
- Palisade Leaf Cell is
adapted for
Photosynthesis
- It packed with Chloroplasts for
Photosynthesis
- Tall shape
- Means that there's a lot of
surface area
- Exposed down the side
for absorbing CO2
- Thin Shape
- Lot packed to the top of
the leaf in a group
- This is most of the Photosynthesis happens
- Guard Cells
- Diagram of Stoma, inside is the Guard cell
- Guard cells are adapted
to open and close pores
in the stoma
- When the plant has lots of
water, the guard cells fill up
and go plump and furgid.
- This make the Stoma open so
gases can be exchanged for
Photosynthesis
- The Stoma opens so gases
can be exchanged for
Photosynthesis
- Red Blood
- Red Blood Cells
- Diagram of Red Blood Cells
- Red Blood Cell are
adapted to carry
Oxygen around the
body
- Concave shape
- Gives it a big surface area
for absorbing oxygen
- Helps them pass smoothly
through the capillaries to
reach the body cells
- Packed full of Haemoglobin
- The pigment to absorb oxygen
- No Nucleus
- More room for haemoglobin
- Sperm and Eggs Cells
- Function of a Eggs cell
- Contain nurishment for early stages of
embyro develpment
- The cell carry the Felmale DNA
- The cell contain huge food
reserves to feed the embyro
- Function of a Sperm Cell
- Basically the sperm job is to
get the Male DNA to the
Female DNA
- Long tail and a streamline
head to help it swim to the
egg
- The mitochondria provide
the energy the sperm needs
- The sperm fuses with the egg
- The egg membrane changes instantly to
stop any sperm from getting in
- This make sure that the offspring has the
right amount of DNA
