Detailed explanation-1: -nucleus. The nucleus is like the remote control center of the cell. It acts as the cell’s brain by telling it what to do, how to grow, and when to reproduce. The nucleus is home to the cell’s genes. A membrane, a thin layer that allows chemicals to pass in and out to the rest of the cell, surrounds the nucleus.
Detailed explanation-2: -The nucleus is called the control center of the cell. This is because it is responsible for maintaining the integrity of DNA. A large fraction of the genome comes from nuclear DNA. Thus, the nucleus controls much of the cell’s activities such as metabolism, growth, and reproduction.
Detailed explanation-3: -The nucleus is called the director of the cell as it controls and conducts all activities of a cell. It keeps genetic information in the form of DNA and chromosomes. It controls the metabolism of the cell. It carries out the function of protein synthesis, which is the source of energy and cellular functions.
