RIBOSOMES

  • Ribosomes are tiny dot like structures made up of RNA and Protein.
  • Ribosomes are also known as protein factory of the cell.

  • They remain spread inside the cytoplasm and on the surface of rough ER.

  • They do not have any cell membrane over it.
  • Ribosomes are the protein builders or the protein synthesizers of the cell.
  • They are present in both prokaryotic and eukaryotic cells.

FUNCTIONS OF RIBOSOMES

  1. They help in the synthesis of protein.

  2. They connect amino acid to form proteins that are essential to carry many cell activities.
