What is the difference between peripheral and integral proteins?
Peripheral proteins are under the phospholipid bilayer, while integral proteins are inscribed in the bilayer.Integral proteins pass entirely through the lipid bilayer of the plasma membrane and have domains that go from the outside of the cell to the cytoplasm inside the cell. While peripheral proteins are only on the one side of the lipid bilayer, either the outside of the cell or the cytoplasmic side inside the cell, but not both.
What do Only eukaryotic cells have?
Plasma membrane, cytoplasm and Nucleus.
The plasma membrane of a cell consists of?
The plasma membrane of a cell consists of the phospholipid bilayer and proteins embeded in lipid bilayer in a mosaic manner . The phospholipid bilayer is formed by phospholipids that have a polar head , and a non-polar tail of fatty acids . Embedded in it, we can find proteins with a variety of functions including the transport of molecules across the membrane, and cell-to-cell recognition.There are 20 to 40 % lipids and 60 to 80 % proteins in plasma membrane .
What does plsma membrane do?
The plasma membrane is a semipermeable barrier that surrounds the cell, regulating the movement of substances in and out of the cell. It also plays a crucial role in cell communication and recognition of other cells. Additionally, the plasma membrane helps maintain the cell's structure and shape.
How do lipid or oil get through plasma cell membrane?
Lipids and oils are able to move through the plasma cell membrane via simple diffusion. The lipid bilayer structure of the membrane allows for the passive and selective movement of non-polar molecules, such as lipids and oils, without the need for energy input.

Proteins attached to only one side of plasma membrane is called what?
Peripheral proteins. http://psych.athabascau.ca/html/Psych402/Biotutorials/1/plasma.shtml?sso=true
Is plasma membrane the feature of eukaryotic cells only?
No.
What do only do eukaryotic?
Plasma membrane, cytoplasm and Nucleus.
What is diffusion and how does it relate to plasma membrane?
Diffusion is simply the movement of one molecule from an area of high concentration to low concentration. It is semi related to the plasma membrane because plasma membrane does allow diffusion, to an extent. Plasma membrane is semipermeable and only allows certain things to diffuse in or diffuse out.

What are the Proteins attached to only one side of the plasma membrane?
Proteins on the outer side of the plasma membrane are usually Glycoproteins and play a variety of roles in cells, one of the most common proteins are receptors. Receptor proteins provide a region for substances such as hormones to bind to, allowing "chemical messsages" to be passed between cells.

Compare and contrast the functions of a cell wall to the functions of a plasma membrane?
The differences between cell wall and cell membrane are:Cell wall is made of cellulose while plasma membrane is made of lipids & proteins.Cell wall is freely permeable but cell membrane is selectively permeable.Cell wall is dead but plasma membrane is living.Cell wall is rigid but plasma membrane is smooth, elastic and flexible.Cell wall is found only in plant cells but plasma membrane is found in all liviing cells.
How do protein channels within the plasma membrane facilitate the movement of substances in and out of a cell?
Protein channels in the plasma membrane act as gateways that allow specific substances to pass through, regulating the movement of molecules in and out of the cell. These channels are selective, meaning they only allow certain substances to pass through based on size, charge, or other characteristics. This helps maintain the cell's internal environment and allows for the efficient transport of essential molecules.

Lipids and oils are able to move through the plasma cell membrane via simple diffusion. The lipid bilayer structure of the membrane allows for the passive and selective movement of non-polar molecules, such as lipids and oils, without the need for energy input.
