Cell Organelles

Structure:-

• double membrane nuclear envelope
• pores
  

Function:-

• nucleolus manufactures RNA and ribosomes
• holds the genetic info
  

Structure:-

• rod shaped
• double membrane
• cristae (folds)

Function:-

• production of ATP
• aerobic respiration
• matrix contains proteins, lipids, DNA and enzymes for respiration

Structure:-

• ribosomes on surface of membranes
• cisternae (flattened sacs)

Function:-

• provides a large surface area for protein synthesis

Structure:-

• no ribosomes on surface
• tubular shape

Function:-

• synthesis of lipids and carbohydrates
• storage of lipids and carbohydrates
• transportation of lipids and carbohydrates

Structure:-

• cisternae (flattened sacs)
• vesicles

Function:-

• forms lysosomes
• adds carbohydate to protein to form glycoprotein
• produces secretory enzymes

Structure:-

• vesicles containing enzymes

Function:-

• digest worn out organelles
• break down dead cells
• break down material ingested by phagocytic cells (e.g. white blood cells)

Structure:-

• small cytoplasmic granules

Function:-

• contain RNA and protein for protein synthesis

Structure:-

• finger-like projections

Function:-

• increase surface area for more efficient absorption
