BIO 114 Chapter 5 Review Questions
and Correct Answers
Fluid Mosaic Model ✅Used to describe a membranes structure
- a patchwork of diverse protein molecules embedded in a phospholipid bilayer

Diffusion ✅Tendency of particles to spread out evenly in an available space

Concentration Gradient ✅Particles move from an area of more concentrated particles
to an area where they are less concentrated

Passive Transport ✅Does not require energy to diffuse across a cell membrane

Osmosis ✅The diffusion of water across a selectively permeable membrane

Tonicity ✅The ability of a surrounding solution to cause a cell to gain or lose water

Isotonic ✅The concentration of solute is the same on both sides of a membrane
- the cell volume will not change

Hypotonic ✅The solute concentration is lower outside the cell
- water molecules move into the cell
- the cell will expand and may burst

Hypertonic ✅The solute concentration is higher outside the cell
- water molecules move out of the cell
- the cell will shrink

Osmoregulation ✅The control of water balance

Facilitated Diffusion ✅The movement of polar and charged substances across a
membrane with the help of specific transport proteins
- no energy
- relies on concentration gradient

Aquaporin ✅Protein channel that allows for rapid diffusion of water in and out of
certain cells

Active Transport ✅A cell must expend energy (ATP) to move a solute against its
concentration gradient
