1. How is the sperm cell adapted to its function?

  • is a prokaryotic cell
  • has an acrosome at the front of the head where is stores enzymes needed to digest its way through the membrane of the egg cell
  • has cilia
  • carries the female DNA to nourish the developing embryo in the early stages

Other questions in this quiz

2. How is an egg cell adapted to its function?

  • has a diploid nucleus
  • its membrane changes structure to stop and more sperm from entering to make sure its has the right amount of DNA (after fertilisation)
  • contains and acrosme
  • has cilia to help move mucus through the airwaves up to the throat so it can be swallowed and not reach the lungs

3. Epithelial cells line the surfaces of organs and contain cilia. What if the function of these cells?

  • to transport the male's DNA
  • helps blood flow to the heart
  • to move substances- the cilia beat to move substances to move in one direction, along the surface of the tissue
  • to carry female DNA to nourish the embryo

4. What do ciliated epithelial cells help?

  • translocation
  • to move mucus through the airwaves so it can be swallowed and not reach the lungs
  • fertilisation
  • nourish the embryo with nutrients

5. How is an egg cell adapted to its function?

  • has lots of mitchondria
  • has a diploid nucleus
  • contains nutrients in the cytoplasm to feed the embryo
  • has a long flagella
