Prokaryotic cells do not have a nuclear membrane.
Virtually all cells contain a cell membrane, including plants and animals.
There are two types of cells, prokaryotic cells and eukaryotic cells. Prokaryotic cells are cells which do not have a proper nucleus. Bacteria are prokaryotes. Eukaryotic cells are cells which do have a nucleus, surrounded by a nuclear membrane. All plants, animals, fungi and protists have eukaryotic cells. There are many other differences between prokaryotic and eukaryotic cells.

A red blood cell, also known as an erythrocyte, is an example of a cell type without a membrane-bound nucleus. These cells lose their nucleus as they mature to make room for hemoglobin, the oxygen-carrying protein they contain.
It Is Basically Cells
Prokaryotic cells do not have a nuclear membrane.
Organisms belonging to the domain Archaea have cells with nuclear material that lacks a nuclear membrane. This type of genetic material organization is referred to as a nucleoid.
Virtually all cells contain a cell membrane, including plants and animals.
First off there are no simple cells that have no membranes, As the simple cells are prokaryotic cells- these cells contrain a cytoplast,and a cell membrane, the other type of cells are eukaryotic cells- these cells contain a cytoplasm, nucleus, cell membrane, and in some cell walls, and mithrocondria, and some have chloroplasts, and they also have Endoplasmic reticilumns, and a Golgi apparatus in most, and they have vacouls. so therefore there are no cells that do not contain a membrane
No, cells have a basic structural similarity in that they are surrounded by a cell membrane, contain cytoplasm, and have a nucleus (in eukaryotic cells). However, their specific structures can vary depending on their function and type.
These are the two categories of cells . A prokaryote is a type of cell without a nuclear envelop and some other cell organelle with out a membrane as in case of bacterial cell. A eukaryote cell has cell organelles enclosed in the cell membrane and has nuclear envelop.
Prokaryotic cells do not contain a nucleus or membrane-bound organelles. They have a single circular chromosome and lack membrane-bound organelles such as mitochondria or endoplasmic reticulum. Examples of prokaryotic cells include bacteria and archaea.
The cells of eukaryotes will contain a nucleus.
Lipo-protein membrane
A eukaryotic cell is a type of cell that has a defined nucleus enclosed by a membrane. These cells also contain other membrane-bound organelles, such as mitochondria and endoplasmic reticulum. Eukaryotic cells are found in plants, animals, fungi, and protists.
membrane
They are any cells with a membrane bound nucleus.
