Question

Pressure gradient is the driving force for this type of passive transport

Answer 1

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.
