   • ells may be specialised to carry out a particular function: sperm Cells, nerve Cells and muscle Cells in animals.
2. How are nerve cells specialised for their function?
   • Nerve Cells have a long shape can conduct electricity so the can send messages between places in the body.
3. How are muscle cells specialised for their function?
   • Muscle Cells have: - a long shape so they can contract causing movement - lots of mitochondria to gain enough Energy through respiration.
4. How are sperm cells specialised for their function?
   • Sperm Cells have: - a pointed head to be streamlined and to poke into the egg Cell - tail to swim - lots of mitrocondria to generate the Energy to swim.
5. What are the names of specialised cells in plants?
   • Cells may be specialised to carry out a particular function: root hair Cells, xylem and phloem Cells in plants.
6. How are root hair cells specialised for their function?
   • Root hair Cells have a large surface area to absorb water and nutrients.
7. How are xylem cells specialised for their function?
   • Xylem Cells in plants have: - no cytoplasm or other organelles, - no Cell walls on the end, so they form a tube - Cell walls strengthened with waterproof lignin To: - transport water around the plant - to strengthen the plant
8. How are Phloem cells specialised for their function?
   • Phloem Cells in plants have: - no cytoplasm or other organelles, - open ends with sieve plates between Cells To: - transport 'phood' around the plant
