Answer» Answer: Nucleus is a spherical structure located in the centre of the cell • It is separated from the cytoplasm by a membrane called nuclear membrane • Nuclear membrane is porous and allows the movement of material between the cytoplasm and inside of the nucleus • The matrix of the nucleus is called nucleoplasm • Dense spherical BODY seen inside the nucleus is called nucleolus • It contains thread like structures called CHROMOSOMES • Chromosomes carry genes. Gene is the UNIT of INHERITANCE. It is the functional unit of chromosome made up of DNA.It HELPS in inheritance of hereditary Explanation:

Answer:

Nucleus is a spherical structure located in the centre of the cell

• It is separated from the cytoplasm by a membrane called nuclear membrane

• Nuclear membrane is porous and allows the movement of material between

the cytoplasm and inside of the nucleus

• The matrix of the nucleus is called nucleoplasm

• Dense spherical BODY seen inside the nucleus is called nucleolus

• It contains thread like structures called CHROMOSOMES

• Chromosomes carry genes.

Gene is the UNIT of INHERITANCE. It is the functional unit of chromosome

made up of DNA.It HELPS in inheritance of hereditary
