The membrane is the most exposed part of the cell, it is chemically active and comes into contact with many chemicals. DNA here would be exposed to possible damage. Having the DNA enclosed in the nucleus and nuclear membrane better protects this very important "director" from potential damage.
This membrane is called the fluid mosaic model as it is a mixture of phospholipids, cholesterol, proteins and carbohydrates. It is mainly phospholipids. The proteins sort of float on the surface of the membrane like islands in the sea.Cholesterol is also found in the membrane. It prevents lower temperatures from inhibiting the fluidity of the membrane and prevents higher temperatures from increasing fluidity.

The outermost living part of a cell is the cell membrane. The cell membrane regulates what comes into the cell and what goes out of the cell. It is composed of a double layer of phospholipids and proteins.
The human cell has three principal parts which are the plasma membrane, cytoplasm, and the nucleus. The outer boundary is the plasma membrane.
diagrams should include the correct orientation of the phospholipids, proteins, carbohydrate, and cholesterol in the membrane.
Plasma membrane is the cell component that forms pinocytic vesicles through the process of endocytosis. Pinocytic vesicles are small membrane-bound vesicles formed by invagination of the plasma membrane to bring in extracellular fluids.
Yes, the plasma membrane is the outermost component of all cells. It acts as a barrier that separates the interior of the cell from its external environment, controlling the movement of substances in and out of the cell.
A prokaryotic cell has DNA, ribosomes, plasma membrane an cytoplasm.
