Answer:

Three important organelles in the cell are nucleus, mitochondria and rough endoplasmic reticulum.

Explanation:

Cellular organelles are structures that are mainly found in all eukaryotic cells and are linked to the fulfilment of their main functions.  In a cell all organelles are important and each one of them fulfills a specific function. Three of the main organelles of the cell are :

  • Cell nucleus: structure that is located in the center of the intracellular space and contains all the genetic information, in the form of DNA.
  • Mitochondria: responsible for hosting all metabolic processes that lead to energy production, such as oxidative phosphorylation.
  • Rough endoplasmic reticulum: it is associated to another important organelle, the ribosome, being in charge of the synthesis, transport and secretion of proteins.

Prokaryotic cells, whose structure is simpler, lack nuclei and most organelles.
