functions of organelles

• Nucleus

  contains the DNA which determines the type of proteins a cell can make. Therefore, the nucleus controls the structure of the cell and the way it functions. Inside is the nucleolus which plays a part in producing proteins
• ribosomes

  amino acids join together to make proteins
• endoplasmic reticulum

  provides a surface for chemical reactions and the channels are used for storing or transporting molecules.
• Golgi body (apparatus)

  modifies proteins and packages them for secretion from the cell. at the edge of the membrane of the Golgi body, small sacs of liquid containing proteins are formed. These sacs, called vesicles, are surrounded by a membrane
• Lysosomes

  break down large molecules by attaching to the vesicles which are formed when particles or liquid are taken into the cell. their digestive enzymes break down the materials inside, they also digest worn out organelles
• Mitochondria

  where cellular respiration occurs which makes energy available for the rest of the cell
• cilia

  moves substances over the surface of the cell
• flagella

  propels or moves the cell
• microtubules

  keeps organelles in one place or move them around the cell
• microfilaments

  move materials around the cytoplasm or moves the whole cell
• cytoplasm

  fills the space between the nucleus and the cell membrane. Organelles are suspended within it
• cytosol

  where most metabolic reactions occur. It also plays a role in controlling the osmotic pressure of the cell and the flow of chemicals into and out of the cell
