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.
