What are organelles in eukaryotic cells?

Organelles in eukaryotic cells are highly specialized structures that perform specific functions necessary for the cell's operation. These organelles are often separated by membranes, which allows for compartmentalization within the cell, enabling different biochemical processes to occur simultaneously and efficiently. The presence of double membranes around certain organelles, such as the nucleus and mitochondria, is particularly important as it facilitates the regulation of molecular traffic into and out of these organelles, enhances metabolic processes, and aids in energy production. This structural organization is crucial for the overall function and regulation of eukaryotic cells, distinguishing them from prokaryotic cells, which lack such compartmentalization.
