Question

The control center of the cell is-
A. The nucleus
B. The cytoplasm
C. The nucleus
D. All of the above

Answer 1

Hint: A cell consists of three major parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie distinct structures called organelles like mitochondria, golgi bodies, ribosome, lysosome, endoplasmic reticulum, etc.
The control center of the cell is ‘Nucleus’.

Complete answer:
The nucleus is considered as the control center of the cell as it performs many major functions like-
- Contains genetic information for the maintenance of structure, reproduction, development, metabolism, and behavior of the human body.
 - It controls cellular activities by directing the synthesis of particular proteins and enzymes.
- It carries all the information for controlling the various components of the cell and keeping it alive.

Additional Information:
- The cytoplasm is the part of the cell that contains the organelles and all the other components of the cell.
- The cell membrane or the plasma membrane is made up of phospholipids, glycoprotein, and proteins. It acts as a barrier which only allows selective movement of substances into or out of the cell.

So, the correct answer is ‘The nucleus’.

Note: The nucleus is an organelle found in eukaryotic cells only. In prokaryotes, the genetic material is enclosed in what is known as ‘nucleoid’. The nucleus contains the genetic material organized in the form of DNA molecules, along with a variety of proteins, to form chromosomes.
