  • Nucleus :
  1. It is responsible for controlling all the cellular activities.
  2. It carries all the genetic information for growth , development , metabolism , reproduction and behaviours.
  3. It regulates protein synthesis.
  4. It includes genetic changes and brings variation which is essential for organic evolution.

  • Mitochondria [ power house of cell ]
  1. They help in synthesis of fatty acid and amino acid.
  2. They also regulate calcium ion concentration inside the cell.
  3. They are the site of thermogenesis [ heat generation ]

  • Endoplasmic reticulum
  1. It acts as a cytoskeleton and gives mechanical support.
  2. It helps in lipid synthesis.
  3. It helps in glycogenolysis.
  4. It forms nuclear envelope during cell division.

  • Ribosomes
  1. They help in synthesis of protein and hence they are called protein factories.
  2. They also store protein for a temporary time.

Hope I helped ! ♡

Have a wonderful day / night ! ツ
