Lack a nucleus and most organelles
WebJun 30, 2024 · We will focus on eukaryotic cells, cells that contain a nucleus. Prokaryotic cells, cells that lack a nucleus, are structured differently. A cell consists of two major regions, the cytoplasm and the nucleus. The nucleus is surrounded by a nuclear envelope and contains DNA in the form of chromosomes. WebAug 1, 2024 · Prokaryotic cells do not have a nucleus, whereas eukaryotic cells do. A nucleus is a large organelle that stores DNA and serves as the cell ’s command center. Single- cell organisms are usually prokaryotic, while multi- cell organisms are usually made of eukaryotic cells.
