Which type of cells contain a nucleus and organelles bound by membranes?

Eukaryotic cells are characterized by the presence of a nucleus and various organelles that are enclosed by membranes. This structural complexity allows for compartmentalization within the cell, enabling specialized functions to occur in distinct areas.

The nucleus houses the cell's genetic material (DNA) and is the control center for cellular activities, including gene expression and replication. The membrane-bound organelles, such as the mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes, all perform specific functions that are crucial for the cell's metabolism, energy production, and waste processing.

While animal and fungal cells are also types of eukaryotic cells, the term "Eukaryotic Cells" encompasses all organisms in this domain, including plants and protists. Therefore, identifying eukaryotic cells as containing organelles and a nucleus is more comprehensive than limiting the response to only animal or fungal cells. Prokaryotic cells, in contrast, do not have a defined nucleus or membrane-bound organelles, which distinguishes them from eukaryotic cells.
