In the previous segment of the chapter ‘Cell Structure and Functions’, we learnt about the process
of Osmosis. In this segment, let us get ourselves introduced to the cell organelle, Nucleus.
What is the Nucleus?
- The controlling unit of the cell is called the Nucleus.
- It is located at the centre of the cell and governs the functions of other organelles.
- It has its own membrane which separates the inner contents of the cell from the rest of the cytoplasm.
- The membrane has pores to allow entry and exit of substances across it.
- The nucleus has its own jelly-like fluid called the Nucleoplasm which is slightly different from the rest of the cytoplasm.
How does the nucleus regulate the activities of other organelles?
The nucleus contains the genetic material which is responsible for the transmission of characters from one generation to the next. The genetic materials are codes for specific proteins which perform various functions in the cell.
For example, passing information, communication, building structures, and many other activities are carried out by specific proteins.
Thus, the nucleus helps in regulating the various functions of the other cell organelles.
