The cell membrane and the membranes of all of their organelles are made of phospholipids.
No No
They are selectively permeable, provides structure to cells.
The cells control center, the nucleus, is surrounded by the cell membrane. The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the phospholipid bilayer with embedded proteins.
A cell membrane is composed of a double layer of phospholipids, more commonly referred to as a phospholipid bilayer, and each phospholipid itself is important to the structure and function of the cell membrane. The head of a phospholipid is hydrophilic, attracting water, the two tails are hydrophobic not attracted to water. This means that water can pass through the cell well by passive transport, as the hydrophilic heads draw the water towards them and the hydrophobic tails push the water through the membrane to the other side. The tails of the phospholipid also play an important function, as the chinks in the tail allow the membrane to be fluid and allow substances to pass through (if they do not require active transport).
an organelle is a small cell structure that carries out a function within the cell. I believe that the function is determined by the shape and size of it because the organelle needs to be a certain size to carry out all of the functions that need to be preformed.
No No
The cell membrane consists of a lipid bilayer which is actually a phospholipid. Cell membranes are semipermiable and they regulate what enters and leaves the cell.
A phospholipid bilayer.
the cell membrane
It hold the structure of the cell together. It also regulate what enters and exits the cell.

phospholipid bi-layer
Cell membrane mainly consists of bilayer phospholipid which makes sure that nothing but water to pass through.
