CB1c-Specialised cells

• How are egg cells adapted to their function?

  -Contains nutrients in the cytoplasm to supply the growing embryo

  -It has a haploid nucleus that can fuse with a sperm's haploid nucleus to create a diploid zygote

  -After fertilisation, the membrane changes so that no more sperm can enter
• How are sperm cells adapted to their function?

  -Has a tail for swimming to the egg cell for fertilisation

  -Many mitochondria around the base of the tail to release energy needed to propel the sperm

  -The acrosome contains enzymes to digest a way through the egg cell membrane
• How are epithelial cells adapted to their function?

  • Epithelial cells line tubes eg. trachea
  • Cillia moves things along the tube such as mucus.
  • This cell has a lot of cilia to move mucus, containing dirt and bacteria away from the lungs
