Cell Organelles

• Describe the structure of the rough endoplasmic reticulum

  
  

  Has ribosomes and a large surface area

  which helps able for protein synthesis
• Describe the structure of the nucleus

  Surrounded by nuclear envelope. Have nuclear pores which allow substances to enter and exit
• Functions of golgi apparatus

  Produces secretory enzymes and carbohydrates

  Stores and modifies proteins and triglyceridesForms vesicles for transporting proteins and triglycerides
• Cell-surface membrane

  The membrane is found around the outside of a cell; It's a phospholipid bilayer.

  It Regulates the movement of substances into and out of the cell.

  It's also got receptor molecules on it, and carrier proteins.

  
• molecules ribosomes are made out of

  • RNA
  • proteins
• smooth endoplasmic reticulum

  • system of membranes with no ribosomes on the outer surface
  • site of synthesis, storage and transportation of lipids and carbohydrates
