Read the following statements and choose the option which is true for them.
a. Simple diffusion in organisms is a slow process
b. Gaseous exchange in plants occurs only by simple diffusion
c. Facilitated diffusion requires transporters
d. Facilitated diffusion shows uphill movement of molecules

A
a, b and c are correct
B
b is incorrect
C
b, c and d are correct
D
Only d is correct

Solution:

Facilitated diffusion shows downhill movement, i.e., along the concentration gradient.
Active transport show uphill movement, i.e., from a low concentration to high concentration.
