What are the specialized structures that perform different jobs in the cell?

Organelles are specialized structures that perform various jobs inside cells. The term literally means “little organs.” In the same way organs, such as the heart, liver, stomach, and kidneys, serve specific functions to keep an organism alive, organelles serve specific functions to keep a cell alive.

Which structure controls the function of all others?

The nucleus regulates all cell activities of the cell. It is also called the cell’s brain or control centre. Karyokinesis is known as the division of the nucleus during cell division. Using the DNA’s genetic information, the nucleus regulates all the cell’s functions, such as growth and metabolism.
