specialised cells

• sperm cells are specialised for reproduction
• nerve cells are specialised for rapid communication
• muscle cells are specialised for contraction
• root hair cells have specialised for absorbing water and minerals
• phloem and xylem are specialised for transporting substences
• sperm cells have a long tail and a streamlined head to help it swim
• sperm cells have a lot of mitochondria in the head for energy needed for swimming
• nerve cells are long and have many branches to carry messages to and from other nerve cells
• muscle cells are specialised for contraction and movement, they have lots of mitochondria for energy
• root hair cells are on surface of the root and have long hairs creating a large surface area to absorb water and minerals
• xylem is hollow in the center and has a large surface area for water to pass through
• phloem has few subcellular structures so it is easier to transport substances
