Cell Structure

• Plasma Membrane 


  Regulates movement of substances in and out of the cell, it also has receptor molecules to respond to hormones.

  
• Cell Wall


  Supports plant cells, made out of cellulose.

  
• Nucleus


  Controls cells' activity.

  DNA contains instruction to make new protein.

  Allows substances to move enbetween nucleus and cytoplasm via nuclear pores.

  Nucleolus make new ribosomes

  
• Lysosome


  Contains digestive enzymes

  Breaks down dead or inactive cells

  
• Ribosome


  Site where proteins are made

  
• Rough Endoplasmic Reticulum (RER)


  Processes and packages proteins made from the ribosomes.

  
• Smooth Endoplasmic Reticulum (SER)

  Synthesises and processes lipids

  
• Vesicle

  Transport substances in and out of the cell.

  Formed on the Golgi apparatus

  
• Golgi Apparatus

  Processes and packages lipids and proteins.

  Makes lysosomes

  
• Mitochondrion


  Site of aerobic respiration.

  Where ATP is produced.

  
• Chloropast


  Site where photosynthesis takes place.

  Full of chlorophyll

  
• Centriole


  Involved in the seperation of chromosomes (metaphase)

  
• Cilia


  Microtubules allow cilia to move

  This is used to move substances along the cell surface
