yes they do. however they do not have membrane-bound organelles

What is the only role of mitosis in a unicellular organism such as an amoeba or a paramecium?
In unicellular organisms like amoebas and paramecia, the only role of mitosis is asexual reproduction. During mitosis, the cell duplicates its genetic material and divides into two genetically identical daughter cells, allowing for population growth and maintenance of the species. This process enables the organism to reproduce rapidly under favorable conditions, ensuring its survival and adaptation.
What role do the cell wall and cell membrane play in a cell?
It is important to remember the following: Animal cell: Cell membrane, Plant cell: Cell membrane, cell wall. The role of a cell membrane is to monitor what exits and enters the cell and therefore maintain the internal environment of it, to contain the contents of the cell and to provide some sort of protection for it. The role of a cell wall which is unique only to plant cells, is to protect the cell inside and lend support to it so it can maintain its stucture.
What are membrane proteins involved in?
The plasma membrane separates the interior of cells from the outside environment. The function of this membrane is to protect the cell from its surroundings. The membrane proteins provide many functions that is vital for survival of the organism. These proteins may act as a membrane receptor and relay signals between the cells internal and external environments. Also transporting proteins by moving molecules and ions across the membrane.
What does the cell membrane do in the egg cell?
the wall. it is necessary to only let things in and out based on what the nucleus of the cell wants. for example the cell membrane will only let sperm in until one has penetrated the egg, then the membrane stops trying to let sperm in.
Does plant cells need a cell membrane?
Yes plant cells need a cell membrane. In addition to the cell membrane they also have a cell wall. Animal cells however do not have a cell wall but merely a membrane. A cell is not able to live without a membrane as it holds the organelles and cytoplasm in place.
What role of the cell membrane and cell wall play in the cell?
Separate the living organism from the nonliving environment around it.
What role does an integral membrane protein play in the structure and function of a cell membrane?
Integral membrane proteins are embedded within the cell membrane and play a crucial role in maintaining the structure and function of the membrane. They help regulate the passage of molecules in and out of the cell, facilitate cell signaling, and provide structural support to the membrane. Overall, integral membrane proteins are essential for the proper functioning of the cell membrane.
What is the role of the cell membrane in cell membrane?
Acts as a protective layer and allows materials to enter or leave.
What role do the cell wall and cell membrane play in a cell?

The role of a cell wall which is unique only to plant cells, is to protect the cell inside and lend support to it so it can maintain its stucture.
What cell part plays a role in diffusion?
The plasma membrane of a cell plays a role in diffusion.
What is the only role of mitosis in a unicellular organism such as an amoeba or a paramecium?
In unicellular organisms like amoebas and paramecia, the only role of mitosis is asexual reproduction. During mitosis, the cell duplicates its genetic material and divides into two genetically identical daughter cells, allowing for population growth and maintenance of the species. This process enables the organism to reproduce rapidly under favorable conditions, ensuring its survival and adaptation.
What is the cell membrane and what is its role?
The cell membrane is the outermost part of the cell. It's function is to protect as well as allows certain things to enter and exit the cell.
What are membrane proteins involved in?
The plasma membrane separates the interior of cells from the outside environment. The function of this membrane is to protect the cell from its surroundings. The membrane proteins provide many functions that is vital for survival of the organism. These proteins may act as a membrane receptor and relay signals between the cells internal and external environments. Also transporting proteins by moving molecules and ions across the membrane.
Why is cholesterol present in the cell membrane?
Cholesterol is present in the cell membrane to help maintain its structure and stability. It also plays a role in regulating the fluidity of the membrane, which is important for the proper functioning of the cell.
Describe the role of the cell membrane?
it protects the cell and also it keeps everything together
