Answer 1

Answer:

Nucleolus (4 ) Stores chemicals and nucleoplasm​

Explanation:

The nucleolus is considered as the brain of the nucleus, covering nearly 25% volume of the nucleus. Primarily, it takes part in the production of subunits that unites to form ribosomes. Hence, nucleolus plays an important role in the synthesis of proteins and in the production of ribosomes in eukaryotic cells.
