Question

Facilitated diffusion is a type of

passive transport, which means it
does not require energy.
Which of the following is an
example of facilitated diffusion?

A. liquid molecules colliding

B. plants bringing nutrients into their roots
from the soil

C. protein channels embedded in the cell
membrane

D. the sodium-potassium pump actively
bringing sodium and potassium into the cell

Answer 1

B

Step-by-step explanation:

The plant doesn't use energy to bring nutrients into the roots. The concentration of nutrients is higher in the soil than in the root, so they passively move into the root to make the concentrations equal.
