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