The control center that controls all the functions of the cell
A
cytoplasm
B
cell wall
C
cell membrane
D
nucleus
Explanation: 

Detailed explanation-1: -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: -Nucleus is known as the control center of the cell as it performs the following functions: The nucleus contains the hereditary material of the cell, the DNA. It sends signals to the cells to grow, mature, divide and die. The nucleus is surrounded by the nuclear envelope that separates the DNA from the rest of the cell.

Detailed explanation-3: -The nucleus, formed by a nuclear membrane around a fluid nucleoplasm, is the control center of the cell. Threads of chromatin in the nucleus contain deoxyribonucleic acid (DNA), the genetic material of the cell.

Detailed explanation-4: -The function of the nucleus is to maintain the integrity of these genes and to control the activities of the cell by regulating gene expression-the nucleus is, therefore, the control room of the cell.
