Nucleus functions:
- acts as a control centre to the cell due to production of mRNA and so protien synthesis
- It also contains the genetic information of the cell
- Assembles ribosomes and RNA
Nuclear envelope: double membrane, extends to form endoplasmic reticulum, it controls entry and exit of materials into the cell. Contains reactions. With every membrane they 'Compartmentalise'
Nuclear pores: allow passage of large molecules e.g RNA
Nucleoplasm: bulk material within nucleus
Chromatin: genetic info within nucleus, is the diffuse form chromosomes take when the cell is not dividing
Nucleolus: spherical body within nucleus thatis involved in production of ribosomes
