✓
Answer
The nucleus is a cell organelle found in eukaryotic cells. It is bound by the membrane and contains the cell’s hereditary information i.e. it contains the information that will be passed on
Structure:
$i.$ The nucleus is surrounded by a membrane known as the nuclear membrane.
$ii.$ The nuclear envelope has pores through which the $\text{RNA}$ and proteins pass through.
$iii.$ The nucleus contains $\text{DNA}$ and $\text{RNA}$ which form chromatin.
$iv.$ When chromatin condenses, it forms chromosomes.
$v.$ There is another structure called nucleolus present inside of the nucleus.
$vi.$ The nucleolus is made up of $\text{RNA}$ and proteins.
$vii.$ There is another substance present inside the nucleus. It is known as the nucleoplasm. It is a gel like substance.
Function:
$i.$ Nucleus is like the brain of the cell.
$ii.$ Nucleus stores the genetic information in the form of $\text{DNA.}$
$iii.$ It is the $\text{DNA}$ that contains all the information regarding how the cell would work.
$iv.$ The nucleus also aids in cell division.
$v.$ It is the nucleus that makes $\text{RNA}$ which is then made into proteins.
