cell structure

• what are two adaptations of a sperm cell?

  has a tail to swim to the ovum and fertilise it

  lots of mitochondria to release energy
• what is the function of a red blood cell?

  transports oxygen around the body
• what is the function of a muscle cell?

  contracts and relaxes to allow movement
• what are two adaptations of a muscle cell?

  1. contains protein fibres which can contract to make the cells shorter
  2. contains mitochondria to release energy
• what is the function of a nerve cell?

  carries electrical impulses around the body
• what is an adaptation of a nerve cell?

  has branched endings to make connections with other neurones and effectors
• what is the function of a root hair cell?

  absorbs mineral ions and water from the soil
• what are two adaptations of a root hair cell?

  1. large surface area so more water and minerals are absorbed
  2. mitochondria to release energy for active transport
• what is the function of a palisade cell?


  enables photosynthesis in the leaf
