» Given Questions:
a) Identity the given diagram.
b) Label the parts A to E.
c) What is the function of parts as B and C.
» Required Answers:
Answer ( a ) :
This is the structure of nucleus.
Answer ( b ) :
A Nucleolus
B Nuclear pore
C Chromatin threads
D Nuclear envelope
E Nucleoplasm
Answer ( c ) :
Function of B ( Nuclear pore ) The function of nuclear pore is to transfer the materials between the nucleoplasm and the cytoplasm.
Function of C ( Chromatin threads ) The function of chromatin material is to carry genes which are responsible for the passage of traits from one generation to another.

More about Nucleus:
- Nucleus was found by Robert Brown.
- Nucleus is a dense body found in the centre of the cell which controls the all activities of the cell.
- They are bounded by two nuclear membranes.
- Nucleus are made from some parts–
- Nuclear Membrane : It is the porous membrane that seperates contents of nucleus from the cytoplasm.
- Nucleoplasm : This is the fluid present in the nucleus.
- Nucleolus : This the small spherical body found in the nucleus. It is made up of nuclear protein and RNA is also present here.
- Chromosomes/Chromatin - They are the thread like structures which carry genes. And they are responsible for the transmission of hereditary traits from rhe parent to offsprings.
- Nucleus regulates the cell cycle.

A) Identity the given diagram.
Ans - Nucleus
The given Diagram is Nucleus
B) Label the parts A to E.
A ➩ Nucleolus
B ➩ Nuclear pore
C ➩ Chromatin threads
D ➩ Nuclear envelope
E ➩ Nucleoplasm
C) What is the function of parts as B and C.
➩ Function of B ( Nuclear pore )
The nuclear pore is a protein-lined channel in the nuclear envelope that regulates the transportation of molecules between the nucleus and the cytoplasm.
➩ Function of C ( Chromatin threads )
The chromatin is a lower order of DNA organization, while chromosomes are the higher order of DNA organization.
