What are the molecules in a plasma membrane that provide basic membrane structure cell identity and membrane fluidity?
Plasma Memberances envelop all plant and animal cells and all single-celled eukaryotes and prokaryotes, seperating them from more.
Selective permeability refers to the fact that the plasma membrane keeps all molecules out of the cell?
Selective permeability refers to the fact that the plasma membrane can choose which molecules to let in or out of the cell.
What are the molecules in the plasma membrane made of?
phospholipids are the molecules that make up the plasma membrane and they are made of polar (hydrophilic) heads and 2 non-polar (hydrophobic) tails
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
Give the Chemical nature of plasma membrane and cell wall?
plasma membrane is made of organic molecules called lipds and proteins

Which structure regulates passage of molecules into and out of cells?
The cell membrane is a membrane separating the inside of the cell from the outside environment. This structure is also known as the plasma membrane or the cytoplasmic membrane.
What are most of the molecules that compose the plasma membrane?
phospholipids
What Molecules in the plasma membrane function as transporters?
Proteins

The plasma membrane is a semipermeable membrane. This means that it is?
it is permeable to some molecules and not permeable to others.
Give the Chemical nature of plasma membrane and cell wall?
plasma membrane is made of organic molecules called lipds and proteins
How do glucose molecules cross a plasma membrane?
Facilitated Diffusion
What is the job of the plasma membrane?
it regulates the entry and exitof the molecules
What 5 molecules form plasma membrane?
