The plasma membrane is:
A membrane composed of tiny shelves or cristae
A phospholipid bi-layer surrounding the cell
A protein bi-layer enclosing the plasma
A single- layered membrane surrounding the nucleus
What are the finger-like projections from a cell membrane that helps increase absorption of a cell?
Microvilli
Cilia
Flagella
Sterocota
When a cell is placed in a hypertonic solution in which the cell is impermeable to the solutes, what will happen to the cell?
The cell will swell from gaining water and burst
The cell will lose water and shrink
The swell will initially shrink until it reaching equilibrium and then return to its normal size
There will be no change in the size of the cell
What is a function of the protein in the plasma membrane?
Forms a lipid bi-layer
Circulates antibodies
Molecular transport through the membrane
Oxygen transport
Passive membrane transport process includes:
Movement of water from an area of low water concentration to an area of high water concentration
Movement of a substance down its concentration gradient
The use of transport proteins moving substances from and area of low concentration to high concentration
Use of ATP
