Write short note on nucleus.
✓
Answer
The nucleus is also known as the 'control centre of the cell'. It is generally centrally placed. It is bounded by a nuclear membrane, in which nuclear pores are present. The fluid inside the nucleus is called nucleoplasm. Nucleoplasm contains a thread-like structure called chromatin and nucleolus. Chromatin contains DNA, which condensed to form chromosomes during cell division. Nucleolus synthesizes ribosomes
