In addition to the nucleus, cell membrane and cytoplasm, other structures can be used using the electron microscope.

The illustration shows the ultrastructure of an animal cell as revealed by an electron microscope. The mitochondria is the site of aerobic respiration and the ribosomes are where proteins are synthesized.

Cells can be thought of as mini factories with jobs being carried out in specialised areas. Each structure is designed in a way that suits its function. Specific organelles carry out their function to ensure the survival of the cell.

You do not need to know the endoplasmic reticulum, lysosomes or Golgi. The plasma cell membrane is simply the cell membrane. The cytoplasm is the light yellow colour inside the cell.
