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.

lipids and cholesterol
Phospholipids
DNA, proteins, plasma membrane
No. Some secrete a covering.
No
diagrams should include the correct orientation of the phospholipids, proteins, carbohydrate, and cholesterol in the membrane.
The barrier that separates the interstitial fluid from the intracellular fluid is the plasma membrane. The interstitial fluid is a major component of the extracellular fluid.
A prokaryotic cell has DNA, ribosomes, plasma membrane an cytoplasm.

The plasma membrane is the structure that is most responsible for maintaining cell homeostasis. The plasma membrane is also known as the cell membrane.
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.
