Answer 1

» 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 $\longrightarrow$ Nucleolus

B $\longrightarrow$ Nuclear pore

C $\longrightarrow$ Chromatin threads

D $\longrightarrow$ Nuclear envelope

E $\longrightarrow$ Nucleoplasm

Answer ( c ) :

Function of B ( Nuclear pore ) $\longrightarrow$ The function of nuclear pore is to transfer the materials between the nucleoplasm and the cytoplasm.

Function of C ( Chromatin threads ) $\longrightarrow$ 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–

1. Nuclear Membrane : It is the porous membrane that seperates contents of nucleus from the cytoplasm.
2. Nucleoplasm : This is the fluid present in the nucleus.
3. Nucleolus : This the small spherical body found in the nucleus. It is made up of nuclear protein and RNA is also present here.
4. 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.

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.
