Where are the cell's chromosomes stored?

1. Cytoplasm

2. Nucleus

3. Ribosomes

4. Endoplasmic reticulum

The correct answer is: Nucleus

The chromosomes of a cell are stored in the nucleus, which serves as the control center of the cell. The nucleus is a membrane-bound organelle that contains the genetic material (DNA) organized into chromosomes. This arrangement allows for the protection of DNA and the regulation of gene expression, as well as facilitating processes such as replication and transcription. The nucleus is central to many cellular functions, providing a distinct environment where genetic information can be accessed and utilized efficiently. This structural organization is vital for cell division and the careful preservation of genetic information across generations. In contrast, other cellular components such as the cytoplasm, ribosomes, and endoplasmic reticulum have different functions related to metabolism, protein synthesis, and cellular transport, but they do not store chromosomes.
