- Specialised Cells
- Animal
- A motor neurone: transmits nerve impulses
- Dendrites - allows for many connections to be quickly made
- Axon (fibre extension) - lets the cells cover a large distance
- Sheath (tissue that covers the nerve) - protects the nerve and allows faster transition
- Muscle Cell: allows movement
- Mitochondria - muscle cells have many mitochondria to release energy for contraction
- Protein fibres - allow the cell to contract, letting the body move
- Sperm Cell: Carries genetic information for reproduction
- Acrosome - contains enzymes to allow the sperm to penetrate the egg
- Nucleus - contains only one set of genetic information
- Mitochondria - Sperm have many of these so they have a large energy production for their journey
- Tail - to propel the sperm to fertile the egg
- A motor neurone: transmits nerve impulses
- Plant
- Root Hair Cell: absorbs water and minerals from soil
- Long extension - Increases surface area
- No chloroplast - roots cells are underground
- Mitochondria - lots of mitochondria for active transport
- Xylem: transports water in plants
- Hardened cell wall - gives the cell strength
- Hollow insides - allows water to move through the cell
- Phloem - transports sugar through the plant
- Perforated cell wall - allows sugar to move through the plant
- Hollow inside with living insides - allows sugar to move through the cell; living cells provide energy
- Root Hair Cell: absorbs water and minerals from soil
- Animal
- Sperm Cell: Carries genetic information for reproduction
- Acrosome - contains enzymes to allow the sperm to penetrate the egg
