Which type of cell contains membrane-bound organelles?

Eukaryotic cells are characterized by the presence of membrane-bound organelles, which are specialized structures within the cell that perform distinct functions. Examples of these organelles include the nucleus, endoplasmic reticulum, mitochondria, and Golgi apparatus, among others. The membrane surrounding these organelles allows for compartmentalization within the cell, enabling more complex processes and greater efficiency in cellular functions.

In contrast, prokaryotic cells, such as bacteria, do not have these membrane-bound organelles. Their cellular structure is more simplified, with no nucleus or other complex organelles, which limits their ability to carry out specialized processes within distinct compartments. This fundamental difference highlights the complexity of eukaryotic cells and their ability to support a wider range of functions and activities, making them distinct in overall structure and function from prokaryotic cells.
