The scientific study of biology covers all of the bases of life, looking at bacteria, animals, plants and oh so much more, but in the following quiz, we’ll be taking a closer look under the microscope to see what little building blocks are used to make up all of these organisms; the cells! What do you know about the cell, its structure, and its many functions? Take the quiz to find out!
- 1.Biological membranes are composed of what? (Check all that apply.)
- A.
Phospholipids
- B.
Proteins
- C.
Fluid mosaic
- 2.
- A.
Enzymes
- B.
Double bond "kinks" in the unsaturated fatty acid layer
- C.
Monosaccharides
- 3.
- A.
None - there is no cholesterol in a phospholipid bilayer.
- B.
The cholesterol helps keep the membrane fluid.
- C.
The cholesterol helps stabilize and keep the bilayer warm and fluid at colder temperatures.
- 4.More than 50 kinds of proteins have been found in the plasma membrane of red blood cells.
- A.
True
- B.
False
- 5.Membranes have selective permeability. What does this mean?
- A.
They do not allow any substances to pass through.
- B.
They allow all substances to pass through.
- C.
They allow some substances to pass through.
- 6.
- A.
The tendency for particles to spread out evenly in an available space.
- B.
A chemical process that releases energy.
- C.
Another word for the photosynthesis process.
- 7.
- A.
The red dye will stay on one side of the membrane.
- B.
All of the red dye will move to the other side of the membrane.
- C.
Some of the red dye will move to the other side until both sides of the membrane are equally filled with red dye molecules.
- 8.Diffusion requires energy from cells.
- A.
True
- B.
False
- 9.
- A.
Nothing
- B.
More water will migrate through the membrane towards the side with MORE glucose molecules

- A.
True
- B.
False
- 12.Animal cells in a hypertonic solution will shrivel up and die.
- A.
True
- B.
False
- 13.Plant cells thrive in an isotonic solution.
- A.
True
- B.
False
- 14.Plant cells shrivel up in hypertonic solutions.
- A.
True
- B.
False
- 15.What is a hypotonic solution?
- A.
A solution with a solute concentration lower than that of a cell
- B.
A solution with a solute concentration higher than that of a cell
- C.
A solution with a solute concentration equal to that of a cell
- 16.
- A.
Transport certain solutes through the cell membrane
- B.
Transport DNA instructions to ribosomes
- C.
Turn the phospholipid bilayer inside-out
- 17.What is an aquaporin?
- A.
A type of blood cell
- B.
A base solution
- C.
A membrane protein that allows the rapid entry and exit of water molecules.
- 18.What does a cell use to move a solute against its concentration gradient (ie, moving a through a membrane to a side where the solute is more concentrated)?
- A.
Aquaporins
- B.
Active transport
- C.
Diffusion
- 19.
- A.
Exocytosis
- B.
Endocytosis
- 20.Kinetic energy is associated with...
- A.

- B.
Light energy (used for photosynthesis)
- C.
Both A and B
- 21.Chemical energy is a potential energy.
- A.
True
- B.
False
- 22.What is cellular respiration?
- A.
The rhythmic breathing of a cell
- B.
Energy conversion (converting "food" energy to ATP)
- C.
Cytoplasmic regulation
