NEET BIOLOGY

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: -A nucleus 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-3: -The nucleus, often considered the “brain” of the cell, contains the cell’s vast genome. The nucleus is primarily responsible for regulating gene expression, which in turn controls the instructions for protein synthesis.

Detailed explanation-4: -Within the cell body is a nucleus (2), which controls the cell’s activities and contains the cell’s genetic material.

Detailed explanation-5: -The nucleus directs and regulates the cell’s functions (such as development and metabolism) and houses the genes, which hold the cell’s genetic information. Hence, due to these functions of a nucleus it is called the brain of the cell.
