Why are there different types of animal cells?
Keywords:
  • Organ : a group of tissues that work together to perform a particular function. (1)
  • Tissue : a group of specialised cells that work together to perform a function. (1)
  • Adaptation : a change that an organism goes through in order to become better suited to its environment. (1)
  • Xylem : the vascular tissue in plants specialised to transport water and dissolved nutrients up the plant. (1)

Cells may be specialised to carry out a particular function: sperm cells, nerve cells and muscle cells in animals. What are the names of specialised cells in animals?

Specialised cell Chinese whispers.
Nerve cells have a long shape can conduct electricity so the can send messages between places in the body. How are nerve 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. How are muscle 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. How are sperm cells specialised for their function?
Cells may be specialised to carry out a particular function: root hair cells, xylem and phloem cells in plants. What are the names of specialised cells in plants?
Root hair cells have a large surface area to absorb water and nutrients. How are root hair 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 How are xylem 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 How are Phloem cells specialised for their function?
Students should be able to, when provided with appropriate information, explain how the structure of different types of cell relate to their function in a tissue, an organ or organ system, or the whole organism.
