• What are the functions of the nucleus?

  • Controlling the cell's activities - It contains DNA with instructions to produce proteins. 
  • Synthesis of ribosomes - The nucleolus makes ribosomal RNA.
  • Exchange between nucleus and cytoplasm - Substances can enter or leave the nucleus via the nuclear pores.
• Label the diagram

  A) Nuclear pore

  B) Nucleolus

  C) Nuclear envlope

  D) Chromatin

  
• What are the functions of the cell surface membrene?

  • Controls movement of substances into and out of the cell - The membrane is partially permeable.
  • Cell signalling - Receptors can detect signals from other cells.
• Label the diagram

  A) Glycoprotien

  B) Glycolipid

  C) Cholesterol

  D) Insintric protien

  F) Phospholipid bilayar

  
• What is the role of Mitochondria?

  Site of aerobic resperation - Produces ATP
• What is the role of Ribosomes?

  Site of Protien synthesis
• What is the role of Golgi Apperatus?

  Process and package lipids and proteins - Carried out by the cisternae.

  Store and transport lipids and proteins - Carried out by the vesicles.

  Synthesise lysosomes - Specialised vesicles.
• What is the role of Rough ER

  • Synthesis and transport of proteins - The proteins are made using the ribosomes.
• What is the role of Smooth ER

  Synthesis, storage, and transport of lipids and carbohydrates - For example, cholesterol and steroid hormones.
• What is the role of Lysosomes?

  Digest pathogens - This process uses enzymes.

  Break down waste material - This material includes old organelles and cells.
