Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
I am the “brain” of the cell. I control all cell activities
A
nucleus
B
lysosome
C
cytoplatelets
D
vacuole
Explanation: 

Detailed explanation-1: -The nucleus is the largest and most significant living organelle of the cell. All cell activities of the cell are regulated by the nucleus. Hence it is called brain or control centre of the cell.

Detailed explanation-2: -The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. The gel-like matrix in which the nuclear components are suspended is the nucleoplasm.

Detailed explanation-3: -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-4: -Because nucleus contains a material called gene which controls all activities of cell and its characteristics. Cell nuclei contain most of the cell’s genetic material, organized as multiple long linear DNA molecules in complex with histones, to form chromosomes.

Detailed explanation-5: -The nucleus, formed by a nuclear membrane around a fluid nucleoplasm, is the control center of the cell.
