Prokaryote cells can live without and do not contain a membrane-bound nucleus. Instead, the DNA they possess is free inside the cell. Eurkaryotic cells possess a membrane-bound nucleus that is essential to many of the ce... More » Science Biology Cells

A cell without a nucleus is classified as a prokaryotic cell. The genetic material of prokaryotic cells is free inside the cytoplasm. Prokaryotic cells do not have a need for compartmentalization, unlike more complex cel... More »

Without a nucleus, multicellular life forms, called eukaryotes, would not exist. According to the Molecular Expressions website from Florida State University, the nucleus acts as the administrative center and information... More »

Human epithelial cells, which are animal cells, and elodea cells, which are plant cells, share many structures because both are eukaryotic cells, or cells with a membrane-bound nucleus. Common structures in animal and pl... More »

Animal cells are eukaryotic cells, or cells that contain a membrane-bound nucleus. The nucleus holds the DNA of the cell that provides the cell with instructions for life. More »

Human cells feature a cell membrane surrounding two compartments: the cytoplasm and the nucleus of the cell. Each cell also has several organelles, or structures with specific functions. More »

Prokaryotic cells lack a nucleus. Bacteria and members of the domain Archaea are prokaryotes, while plants, animals, protists and fungi are eukaryotes. Prokaryotic cells lack the membrane-bound organelles found in eukary... More »
