cell differentiation and stem cells

Cards (14)

  • name three specialised animal cells
    sperm cells, nerve cells and muscle cells
  • name three examples of specialised plant cells
    root hair cells, and phloem and xylem
  • how are sperm cells specialised
    streamline head to help it swim through the vagina
    lots of mitochondria to provide enough energy
    enzymes to digest through egg cells membrane
  • how are nerve cells specialised
    long to cover a long distance
    have dendrites to connect to other nerve cells and form a network throughout the body
  • how are root hair cells specialised
    no chloroplasts as its underground
    grows into long hairs, its shape gives a large surface area
  • how are muscle cells specialised
    lots of mitochondria to generate energy needed for contractions
  • differentiation is the process where a cell becomes specialised for a specific function
  • a specialised cell is a cell that is adapted for a specific function
  • a fertilised egg cell is called a zygote
  • a sex cell is called a gamete
  • two types of stem cell found in animals are called embryonic stem cells and adult stem cells
  • embryonic stem cells can be cloned to be made to differentiate into most different types of human cells
  • examples of specialised animal cells are sperm cells, muscle cells and nerve cells
  • examples of specialised plant cells are the root hair cells, phloem and xylem
