What organelle controls the cell?
A
Lysosome
B
Nucleus
C
Nucleolus
D
Chromosomes
Explanation: 

Detailed explanation-1: -The nucleus is the most important organelle of the cell which controls all the cellular activity. It contains the genetic material in the form of DNA which is protected by the nuclear envelope.

Detailed explanation-2: -Nucleus. Known as the cell’s “command center, ” the nucleus is a large organelle that stores the cell’s DNA (deoxyribonucleic acid). The nucleus controls all of the cell’s activities, such as growth and metabolism, using the DNA’s genetic information.

Detailed explanation-3: -A nucleus, as related to genomics, is the membrane-enclosed organelle within a cell that contains the chromosomes. An array of holes, or pores, in the nuclear membrane allows for the selective passage of certain molecules (such as proteins and nucleic acids) into and out of the nucleus.

Detailed explanation-4: -The nucleus is particularly important among eukaryotic organelles because it is the location of a cell’s DNA. Two other critical organelles are mitochondria and chloroplasts, which play important roles in energy conversion and are thought to have their evolutionary origins as simple single-celled organisms.

Detailed explanation-5: -Nuclear pores, small channels that span the nuclear envelope, let substances enter and exit the nucleus. Each pore is lined by a set of proteins, called the nuclear pore complex, that control what molecules can go in or out.
