Cell Organisation

• What are the basic building blocks of all living organisms?

  Cells
• What is the role of specialised cells?

  They carry out a particular function
• What is the process called when cells become specialised?

  Differentiation
• When does differentiation occur in multicellular organisms?

  During the development of the organism
• How are specialised cells organised in multicellular organisms?

  • Specialised cells form tissues
  • Tissues form organs
  • Organs form organ systems
• What do large multicellular organisms have for exchanging materials?

  Different systems inside them
• What is a tissue?

  A group of similar cells working together
• What does muscular tissue do?

  Contracts to move whatever it's attached to
• What is the function of glandular tissue?

  Makes and secretes chemicals like enzymes
• What does epithelial tissue do?

  Covers some parts of the body
• What is an organ?

  A group of different tissues working together
• What tissues make up the stomach?

  Muscular, glandular, epithelial tissues
• What does muscular tissue do in the stomach?

  Moves the stomach wall to churn food
• What is the role of glandular tissue in the stomach?

  Makes digestive juices to digest food
• What does epithelial tissue do in the stomach?

  Covers the outside and inside of the stomach
• What is an organ system?

  A group of organs working together
• What is the function of the digestive system?

  Breaks down and absorbs food
• What organs make up the digestive system?

  Glands, stomach, small intestine, liver, large intestine
• What do glands in the digestive system do?

  Produce digestive juices
• What is the role of the stomach in digestion?

  Digests food
• What does the liver produce?

  Bile
• What is the function of the small intestine?

  Absorbs soluble food molecules
• What does the large intestine do?

  Absorbs water from undigested food
• How is an organism structured in terms of organisation?

  • Organ systems consist of organs
  • Organs consist of tissues
  • Tissues consist of cells
• What does it mean that the bladder is an organ?

  It is made of different tissues working together
