Q- Name various parts of a nucleus and give their functions.
Answer- Nucleus of a cell is consisted of four major parts. These are as follows with their functions:
1. Nuclear membrane:
Nuclear membrane is the outer most layer of the nucleus that seperates the fluid inside the nucleus from the cytoplasm present in the cell.
Function of Nuclear membrane:
Nuclear membrane help in the regulation of materials between nucleoplasm and cytoplasm and also seperates the fluid inside the nucleus from the cytoplasm present in the cell.
2. Neucleoplasm:
Nucleoplasm is the fluid present inside the nucleus.
Function of Neucleoplasm:
Neucleoplasm acts as skeleton of the nucleus and is involved in formation of spindle protein.
Nucleolus:
Nucleolus is the material present inside the nucleus of nucleus.
Function of Neucleolus:
Nucleolus helps in formation and store house of r-RNAS.
Nuclear chromatin (Chromosomes):
Nuclear chromatin (Chromosomes) is the genetic material that is present inside the nucleus of nucleus.
Function of Nuclear chromatin (Chromosomes):
Nuclear chromatin (Chromosomes) helps in the transmission of heredity or genetic characters from parents to offspring.
