$\bold\gray\dag \orange{\underline{\boxed{\sf {Nucleus (Definition) : }}}}\bold\gray\dag$

• It's a Power house of Cell.
• And also it is a small, round and membrane bound structure found in cell.
• It is being surrounded by different layers.

$\sf {\underline{\boxed{ \odot \mid\sf {\blue{ Nuclear \: Envelope : }}}}}$

• It is a double membrane, which separates the nucleus from cytoplasm. It has several nuclear pores. These pores help in exchange of materials between nucleus and cytoplasm.

$\sf {\underline{\boxed{ \odot \mid\sf {\blue{ Nucleoplasm : }}}}}$

• It is the colorless, dense fluid within the nucleus in which chromatin material and nucleus are suspended.

$\sf {\underline{\boxed{ \odot \mid\sf {\blue{ Nucleolus : }}}}}$

• It is a round structure found inside the nucleus.
• It is not bounded by a membrane. It is rich in RNA and protein.
• It is the site of ribosome formation.
• RNA synthesizes protein in the cytoplasm.
• It is also known as mother/factory of ribosomes.

$\sf {\underline{\boxed{ \odot \mid\sf {\blue{ Chromatin \:\: material : }}}}}$

• It is intertwined mass of thread like structures made of DNA and protein.
• During cell division, chromatin becomes highly condensed, thick rod like structures, known as Chromosomes.
