What do eukaryotic cells contain?

Eukaryotic cells are characterized by the presence of a membrane-bound nucleus, which houses their genetic material, and various other organelles that perform specialized functions. These organelles include structures such as mitochondria, endoplasmic reticulum, and Golgi apparatus, among others. The nucleus acts as a control center for cell activities, including gene expression and replication. The additional organelles contribute to processes such as energy production, protein synthesis, and transportation within the cell. This complexity allows eukaryotic cells to perform a wider range of functions than prokaryotic cells, which lack a defined nucleus and internal compartmentalization. Thus, the presence of both a membrane-bound nucleus and other organelles is a key feature that distinguishes eukaryotic cells from other cell types.
