Quick explanation

Indicate that specialized cells perform specific functions, including: (a) ciliated cells for mucus movement in the trachea and bronchi, (b) root hair cells for absorption, (c) palisade mesophyll cells for photosynthesis, (d) neurones for conducting electrical impulses, (e) red blood cells for oxygen transport, and (f) gametes (sperm and egg cells) for reproduction

  • This point belongs to Cell structure, especially Cell structure outcomes.
  • You need to be able to indicate that specialized cells perform specific functions, including: (a) ciliated cells for mucus movement in the trachea and bronchi, (b) root hair cells for absorption, (c) palisade mesophyll cells for photosynthesis, (d) neurones for conducting electrical impulses, (e) red blood cells for oxygen transport, and (f) gametes (sperm and egg cells) for reproduction.
  • The key ideas to know are State.
  • Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
