Answer:
a. osmosis
: Diffusion of water across a semi-permeable membrane.
b. diffusion
: Process that causes red dye to uniformly color a beaker of water red.
c. facilitated diffusion
: Type of passive transport where glucose is "helped" across the membrane.
d. phagocytosis
:
e. pinocytosis
: Process by which the cell brings water droplets into the cell.
f. hypertonic
: Describes a solution that is more concentrated than the inside of a cell.
g. hypotonic
: Describes a solution that is less concentrated than the inside of a cell.
h. isotonic
i. filtration
: Pressure gradient is the driving force for this type of passive transport.
j. exocytosis
: Process by which a cell eliminates waste.
k. equilibrium
: State in which all particles in solution are evenly spaced from one another.
l. active transport: Process that moves molecules from low to high concentrations.
Explanation:
Passive Transport:
- Cellular transport that occurs without expenditure of energy. Types include:
- Diffusion which is the movement of substances down the concentration gradient from high to low concentration across a semi-permeable membrane.
- Osmosis is the movement of water molecules from high water (low solute) to low water (high solute) concentration.
- Facilitated diffusion is the diffusion of substances across membranes via channel or membrane proteins.
Active Transport:
- Cellular transport that requires energy.
Type of Solutions:
- Hypertonic solutions are more concentrated than the cellular environment.
- Hypotonic solutions are less concentrated than the cellular environment.
- Isotonic solutions possess same concentration as cellular environment.
