- cell specialisation
- nerve cell
- specialised to carryelectrical impulses and provide rapid communication
- lots of dendrites to connect with other nerve cells
- long axon that transfers nerve impulses
- synapse, pass impulses between nerve and muscles - contain lots of mitochondria
- specialised to carryelectrical impulses and provide rapid communication
- muscle cell
- muscles contract and relax in pairs to move the bones of the skeleton
- contain special proteins which make the fibres contract
- contain many mitochondria to transfer energy
- store glycogen used in cellular respiration to transfer energy needed for fibres to contract
- muscles contract and relax in pairs to move the bones of the skeleton
- sperm cell
- sperm contain the genetic information from the male parent
- a long tail to that helps move the sperm
- middle section full of mitochondria which transfer energy
- nucleus contains genetic information
- acrosomes store digestive enzymes to break egg wall
- sperm contain the genetic information from the male parent
- phloem cell
- transport tissue that moves food
- cell walls allow water carrying dissolved food to move freely
- transfer energy needed to move this food
- transport tissue that moves food
- xylem cells
- transport tissue in pants that carries water and mineral ions
- spirals that make them strong and withstand the pressure of water
- cells die and form hollow tubes for water and mineral ions to move through
- transport tissue in pants that carries water and mineral ions
- root hair cell
- the root hair cells help them to take up water and minerals effectively
- surface area increased so water moves
- large permanent vacuole that speeds up water movement
- many mitochondria that transfer the energy needed for the active transport
- the root hair cells help them to take up water and minerals effectively
- photosynthesis cells
- contain chloroplasts to trap light for photosynthesis
- continlayers to absorb as much uous layers to absorb as much light as possible
- large permanent vacuole that keeps the cell rigid
- nerve cell
