Receptors of protein hormones are present in plasma membrane but for steroid hormones no membrane receptors are needed as they can enter cell membrane , mobile receptors pic steroid hormones from cell membrane and carry them to nucleus .
lipids
Plasma membrane
plasma membrane is made of a bilayer of lipids (or phospholipids) and protiens located inside and outside the same.
The plasma membrane is the limiting membrane of a cell. It is called Phospholipid Bilayer because it consists of proteins and lipids.

The plasma membrane is the limiting membrane of a cell. It is called Phospholipid Bilayer because it consists of proteins and lipids.
All (mostly) membranes of the cell including those of organelles are made up of lipids, proteins and polysaccharides (like cholesterol). The lipids and proteins are called glycolipids and glycoproteins.
Lipids or oil get through plasma membrane because plasma membrane is a selectively permeable membrane. It allows entry and exit of only some substances through it.
