Detailed explanation-1: -Nucleus is considered as the controlling centre of the cell as it controls all the activities of the cell.

Detailed explanation-2: -Definition. The nucleolus is a spherical structure found in the cell’s nucleus whose primary function is to produce and assemble the cell’s ribosomes. The nucleolus is also where ribosomal RNA genes are transcribed.

Detailed explanation-3: -A small spherical or oval organelle, the nucleus, is typically found near the centre of a cell. The genes within the nucleus control the development of the various traits of the cell by controlling the synthesis of specific proteins.

Detailed explanation-4: -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-5: -The correct option is B Nucleus. Nucleus is the control central of the cell. Inside its fully-enclosed nuclear membrane, it contains the majority of the cell’s genetic material.
