Detailed explanation-1: -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-2: -Another organelle in the cell is the endoplasmic reticulum (ER). While the function of the nucleus is to act as the cell brain, the ER functions as a manufacturing and packaging system. It works closely with the Golgi apparatus, ribososmes, mRNA, and tRNA.
Detailed explanation-3: -The nucleus is known as the cell’s control center because it regulates gene expression and facilitates DNA replication during the cell cycle. With an average diameter of 6m, the nucleus is the largest structure of animal cells.
Detailed explanation-4: -The nucleus of eukaryotic cells is similar to the brain of the cell. It contains the genetic information (DNA) and directs the cell how to function.
