Specialisation & Differentiation

• The changing of the stem cell into a type of cell is differentiation
• The final form a differentiated cell is called specialised
• Adult stem cells are multipotent
• Embryotic stem cells are pluripotent
• Adult stem cells can be found in bone marrow
• Pluripotent cells can develop into all cell types that make up the body
• Multipotent cells can develop into some cell types that make up the body
• What is a group of specialised cells that work together to perform a function?

  Tissue
• Hierarchal organisation of organelles - organisms (smallest to largest)
• Hierarchal organisation of organelles - organisms (smallest to largest)

  1. Organelles
  2. Cells
  3. Tissues
  4. Organs
  5. Systems
  6. Organisms
• Tissues are specialised
• A structure made of different types of tissues to perform a shared function is called a/an organ
• Tissues in a/an organ are arranged in a certain order depending on the function it must perform
• Human organs:

  • Heart
  • Lungs
  • Kidneys
• Plant Organs:

  • Roots
  • Stem
  • Leaves
• A system is a group of organs that work together to perform an aspect of bodily function
• Blood cells have an indent to allow for quick oxygen diffusion
