- It carries all the genetic information for growth , development , metabolism , reproduction and behaviours.
- It regulates protein synthesis.
- It includes genetic changes and brings variation which is essential for organic evolution.
- Mitochondria [ power house of cell ]
- They help in synthesis of fatty acid and amino acid.
- They also regulate calcium ion concentration inside the cell.
- They are the site of thermogenesis [ heat generation ]
- It acts as a cytoskeleton and gives mechanical support.
- It helps in lipid synthesis.
- It helps in glycogenolysis.
- It forms nuclear envelope during cell division.
- They help in synthesis of protein and hence they are called protein factories.
- They also store protein for a temporary time.
Hope I helped ! ♡
