The cell membrane is composed of different kinds of molecules. The phospholipid chains surround the cell and is what the cell membrane is primarily made of. Around the cell, you can also find proteins embedded on or all the way through the cell. This protein helps large molecules from outside the cell or inside the cell to go in or out. Between the phospholipid is also cholesterol which helps the cell membrane fluidity.
This all being said, there are three things that make up the cell membrane:
# The phospholipid bilayer
# The protein inside and outside the cell # cholesterol between some phospholipid chains.

Which part allows or prevents substances to go into and out of the cell?
The cell membrane acts as the barrier and transport proteins present in the membrane, such as globular proteins, transport molecules across cell membranes.
What are the molecules that give the cell membrane a mosaic structure?
protein molecules in the cell membrane gives the mosaic structure .
Which type of membrane surrounds a cell?
this is the cell membrane made primarily of lipid molecules with proteins incorporated into it that aid in transport of molecules across the membrane
Why do passenger molecules need to be helped by the carrier protein?
Some molecules can't go through the cell membrane.
What do cell membrane do that cell walls can't do?
Cell membrane is selectively permeable membrane, therefore it allows selective molecules to be taken in by the cell and excludes others. Whereas cell wall is permeable in nature and does not inhibit the intake of many molecules what the cell membrane does.
What types of molecules can easily go through your cell membrane are permeable to the cell membrane?
Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.
What are the two major types of active transports?
The two major parts of active transport are endocytosis and exocytosis. Endocytosis is taking material into the cell by means of infoldings in the cell membrane. There are two types of endocytosis: phagocytosis (large molecules) and pinocytosis (small molecules). Exocytosis is the release of materials from a cell. The vacuole membrane and the cell membrane fuse together and the contents are released.

How do small molecules get through the cell membrane against a concentration?
How do small molecules get through a cell membrane
Molecules can pass through the cell membrane of the human cell?
The molecules that can pass through the cell membrane of the human cell include water. Other molecules include fat soluble vitamins.
What are the molecules that give the cell membrane a mosaic structure?
protein molecules in the cell membrane gives the mosaic structure .
What is made up of a mixture of many types of molecules and is very thin and selective permeable?
cell membrane

this is the cell membrane made primarily of lipid molecules with proteins incorporated into it that aid in transport of molecules across the membrane
Why do passenger molecules need to be helped by the carrier protein?
Some molecules can't go through the cell membrane.
The cell membrane contains lipid molecules that?
The cell membrane contains lipid molecules that provide a barrier to the free movement of ions into and out of the cell.
Which part of the cell surrounds the cell and allows molecules in and?
The cell membrane is the thing that surrounds the cell. The cell membrane contains proteins that allow active transport of molecules in and out of the cell.
