What part of the cell contains the genetic material?

The nucleus is the part of the cell that contains the genetic material, which is organized into chromosomes made of DNA. This organelle serves as the control center for the cell, regulating gene expression and overseeing the processes of cell growth, division, and development. The genetic material within the nucleus is crucial for the replication of DNA and the synthesis of RNA, which is essential for producing proteins necessary for various cellular functions.

The cytoplasm contains various organelles and the cellular components, but it does not store genetic information. Ribosomes are responsible for protein synthesis and do not contain genetic material. The cell membrane is a protective barrier that surrounds the cell, regulating what enters and exits but does not contain genetic information itself. Therefore, the nucleus stands out as the correct answer, as it is specifically designed to house and manage the cell's genetic material.
