Answer:
Fibrous proteins are generally composed of long and narrow strands and have a structural role.
Globular proteins generally have a more compact and rounded shape and have functional roles.
Explanation:
fibrous proteins ARE something, whereas globular proteins DO something.
Plasma membrane is a part of the cell made of a lipid bilayer and an embedded protein layer. It protects the cell from the surroundings and also controls the materials leaving or entering the cell. The membrane is semipermeable and therefore allows certain materials to enter or leave the cell. In this case, the plasma membrane may prevent unlimited flow of water into or out of the cell.
