Answer 2

HLO MATE HERE IS UR ANSWER.

❤. STRUCTURE OF NUCLEUS ❤

⭐. Nucleus has four main parts. They are

• Nuclear envelope.
• Nuclear matrix.
• Chromatin material.
• Nucleolus.

❤. NUCLEAR ENVELOPE ❤

⭐. It consists of two parallel membrane with nucleoplasm inside.

⭐. The outer membrane is continuous with Endoplasmic Reticulum {ER} , which is coated by ribosomes .

⭐. Minute pores are present on the membrane called nuclear pores.

❤. NUCLEAR MATRIX (or) NUCLEOPLASM❤

⭐. It is homogeneous , semi solid substance filled inside the nucleus.

⭐. It is composed of glycoproteins, ribonucleo proteins, hydrolyzing enzymes, DNA and RNA polymerase.

❤. CHROMATIN MATERIAL❤

⭐. The darkly stained network like substance in nucleoplasm is called chromatin material.

⭐. It contains DNA and histones.

❤. NUCLEOLUS ❤

⭐. One ore more spherical bodies present in the nucleoplasm are called nucleoli.
