Question

question 20 of 32
match the descriptions to the appropriate type of transport.
passive transport
active transport
answer bank
requires energy
does not require energy
moves substances from an area of high concentration to an area of lower concentration
moves substances from an area of low concentration to an area of higher concentration

Explanation:

Passive transport relies on concentration gradients (high to low) and no energy input. Active transport moves against gradients (low to high) and needs energy (e.g., ATP). These are core characteristics distinguishing the two transport types.

Answer:

Passive transport: does not require energy, moves substances from an area of high concentration to an area of lower concentration
Active transport: requires energy, moves substances from an area of low concentration to an area of higher concentration
