Cells that have a nucleus are referred to as eukaryotic cells. The nucleus serves as the control center of the cell, housing the cell’s genetic material (DNA) and regulating various cellular activities such as growth, metabolism, and reproduction.
Unlike prokaryotic cells, which do not contain a nucleus, eukaryotic cells can be found in a variety of organisms, including plants, animals, fungi, and protists. The presence of a nucleus allows for more complex processes and structures within these cells, enabling them to perform specialized functions. In addition to a nucleus, eukaryotic cells also have other membrane-bound organelles, such as mitochondria and endoplasmic reticulum, contributing to their complexity.
